SUMMARY:Advanced x-ray imaging of carbon fiber microstructure
DESCRIPTION:Manufacturing defects are a complex and often expensive problem in carbon fiber composites. Understanding the underlying causes of various defects requires accurate characterization and\, ideally\, quantification. Characterizing fiber-level defects can be very difficult\, as they cannot typically be resolved by conventional x-ray or ultrasonic imaging. While 2D sectioning methods can be used to study such defects\, this approach is destructive and may not always capture higher-dimensional features. \nFiber microstructure can however be imaged in 3D using advanced x-ray imaging techniques like synchrotron-based computed tomography (CT). Using this technique\, we can non-destructively image subtle fiber-level features like wrinkling\, misalignment\, and fiber-particle interactions in 3D. This type of imaging can even be done in situ\, to capture defects as they form during the curing process or for different part geometries. \nThis talk will cover results of recent collaborations between the Composites Research Network and the Canadian Light Source (Canada’s national synchrotron facility) to develop new tools to characterize fiber-level defects and better understand how they form. \nPresenter: \nToby Bond\nSenior Scientist\, Canadian Light Source Inc. \nContent discussed in the webinar is linked to the Knowledge in Practice Centre\, allowing users to access this and other content in a consistent and coherent manner.

SUMMARY:Implementation of Bolted Joints in Composite Materials
DESCRIPTION:The majority of parts composed of composite materials are joined with other parts before becoming the final product. In addition to adhesive bonding\, bolted joints are a common method of joining composites. They can be strong\, and reliable\, while allowing for disassembly if required. \nIn a previous AIM Event webinar\, “Introduction to Bolted Joints in Composites”\, advantages and disadvantages\, the working principles of joints\, failure modes\, fastener types\, and design considerations was presented. A recording of this can be found at: https://compositeskn.org/KPC/A369. \nThis webinar will further explore details of the implementation of bolted joints in composites. Including the effect of laminate layup schedules\, joint and fastener dimensions\, hole preparation and tolerance\, and standard mechanical tests used to characterize joints. Results of in-house testing will be used to demonstrate various information presented. \nPresenter: \nDr. Casey Keulen\,\nUniversity of British Columbia \nContent discussed in the webinar is linked to the Knowledge in Practice Centre\, allowing users to access this and other content in a consistent and coherent manner.

SUMMARY:Introduction to Non-Destructive Testing of Composite Materials
DESCRIPTION:Non-Destructive Testing (NDT) is commonly used to assess the quality and current condition of composite materials. It is used to provide insight into the presence of defects and/or the extent of damage without destroying the part\, thereby allowing it to go back into service if appropriate. Many parts go through NDT before being put into service as part of QA procedures. \nThis webinar delves into the fundamentals of non-destructive testing (NDT) for composites\, with an emphasis on Infrared Thermography\, Ultrasound Testing\, and Computed Tomography. It will introduce the main manufacturing defects and lifetime discontinuities\, discussing how to address these with the aforementioned NDT methods. The session will illustrate the practical applications and real-world effectiveness of these NDT methods in composite materials. \nPresenter: \nMarco Didonè\nUniversity of British Columbia \nContent discussed in the webinar is linked to the Knowledge in Practice Centre\, allowing users to access this and other content in a consistent and coherent manner.

SUMMARY:Viscoelasticity and Composite Materials
DESCRIPTION:Polymer matrix composites exhibit viscoelastic behaviour that may affect the long-term performance of the composite structure. Viscoelastic materials display energy dissipation and a memory effect meaning that past mechanical and thermal loads will alter the material. The determination of the material properties and the prediction of their long-term response requires a range of experimental\, computational\, and analytical techniques. \nThis webinar will introduce the fundamentals of viscoelasticity in polymers. These fundamentals will be used to describe common analytical techniques that may impact classical laminate plate theory\, and material parameters that are required for computational and analytical models. Creep\, stress relaxation\, and frequency based experimental techniques will be presented including the required equipment\, data processing approaches\, and potential pitfalls. \nParticipants will gain a basic understanding of viscoelastic challenges in polymer composites\, and be exposed to simple techniques for a first approximation of viscoelastic effects in their analyses. \nPresenter:\nCraig Merrett\, \nAssociate Professor\nClarkson University \nContent discussed in the webinar will appear on the Knowledge in Practice Centre\, allowing users to access this and other content in a consistent and coherent manner.

SUMMARY:Introduction to Tooling for Composite Materials Processing
DESCRIPTION:A composite part requires some form of tooling to take shape during the curing or crystallization process. The tooling will also assist in the deposition and alignment of fibre as well as provide the surface finish of the part. Tooling must be able to stand up to the processing requirements such as temperature and pressure required for the composite part and last for many cycles of production. \nIn this webinar\, different materials and construction methods used for tooling are discussed along with basic functions and requirements. Different tooling concepts for different processes will also be explored along with case studies and examples to illustrate the wide variety of options available. \nPresenter: \nDr. Casey Keulen\nDirector\, Knowledge in Practice Centre\nAssistant Professor of Teaching\, Department of Materials Engineering\, UBC\nCo-Director\, Master of Engineering Leadership\, AMM Program\, UBC \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Introduction to Composites Sustainability
DESCRIPTION:It was thought that the use of composite materials would lead to a net positive environmental impact through their use in aircraft\, wind turbines\, and hydrogen pressure vessels\, among other applications. The reality is that most manufacturing practices used to produce these composite parts are highly inefficient\, producing copious amounts of waste for which we have limited solutions outside of landfilling or incineration. Structures reaching their end-of-life represent a more daunting challenge as they are often contaminated with other materials. \nIn this webinar\, we will first take a look at the current status of composites manufacturing and end-of-life waste across several key sectors. We will then illustrate the challenges recyclers face\, look at current academic and industrial sustainability efforts\, and close with perspectives on the possibility of a circular economy within our community. \nPresenter: \nAdam Smith\nDepartment of Mechanical Engineering\, ETS\nUniversity of Quebec \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:AIM Webinar: Porosity in Composite Materials - Part 2
DESCRIPTION:Composite materials inherently contain defects\, which introduce variability and often restrict their mechanical properties. Among these defects\, porosity is one of the most prevalent and can negatively affect both the structural integrity and aesthetics of the material. The presence and extent of porosity are largely determined by processing parameters. \nPreviously\, we presented a comprehensive list of common causes of porosity along with considerations for reducing or eliminating them (sources and sinks). In this webinar\, we will continue to investigate the sources and sinks of porosity\, particularly focusing on liquid composite molding and advanced manufacturing techniques such as prepreg and out-of-autoclave prepreg processing. We will delve into the formation of porosity within these processes and present case studies. Critical steps like debulking and degassing will be thoroughly discussed. Additionally\, we will provide an overview of the methodologies for measuring and assessing the levels of porosity in a manufactured composite component. \nNote: Recording of Part I of this topic can be found here: https://compositeskn.org/KPC/A336 \nPresenter: \nCasey Keulen\nUniversity of British Columbia \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:AIM event: Porosity in Composite Materials
DESCRIPTION:Defects are inherent in composite materials. They are a source of variability and often become the limiting factor of mechanical properties. Porosity is one of the most common defects found in composite materials. It can compromise the structural integrity and negatively affect aesthetics. It’s presence and extent are a direct outcome of processing parameters. \nIn this webinar\, a comprehensive list of sources and sinks of porosity will be presented and explained. Common causes of porosity will be examined along with considerations for reducing or eliminating them. A number of case studies will be presented to demonstrate the process of identifying the sources of porosity in a composite part. \nPresenters: \nCasey Keulen and Gavin Tao\nUniversity of British Columbia \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Pultrusion of thermoplastic composites
DESCRIPTION:Pultrusion is an automated composite manufacturing process allowing the continuous production of constant cross-section beams. Pultrusion has been successfully used in the industry with thermoset polymers. The pultrusion of thermoplastic polymer composites\, however\, has not reached the same level of industrial penetration. This is mostly due to the high viscosity of melted thermoplastic polymers that hinders impregnation as well as surface finish issues. \nIn this webinar\, we will discuss the scientific and technical challenges that were solved to mature this technology. Results will be presented with a wide range of reinforcements such as flax\, glass\, carbon combined with polymers such as polypropylene\, nylon\, polyetherimide\, and polyetheretherketone. An application of the process: pultrusion of beams with off-axis properties will be covered. The presentation will finally discuss some applications of the technology and how to assess if it is suitable for your applications. \nPresenter: \nLouis Laberge Lebel\nAssociate Professor at Polytechnique Montréal \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Simulation models for rapid liquid composite molding
DESCRIPTION:High-fidelity prediction of the performance of composite structures is helpful for product development and is used increasingly more often by industry. The type of manufacturing process and process conditions will influence the material microstructure and induce defects\, which will ultimately impact part performance. Liquid composite molding processes utilizing dry reinforcement fabrics and snap-cure liquid resins provide an efficient means to manufacture composite parts and have been adopted in several industry sectors. However\, these processes typically involve automated fabric preforming and rapid resin infiltration/curing stages\, which may introduce defects such as fabric wrinkling\, unintended fiber orientations\, and non-uniform degree-of-cure. Process simulation models can be used to predict local and macroscopic process-induced defects\, and when coupled with performance simulation models enable the performance prediction of as-manufactured parts. \nIn this webinar\, the discussion will focus on applications and implementation of an integrated process and performance simulation platform for high-pressure resin transfer molded non-crimp fabric/snap-cure epoxy composite parts subjected to impact loads. \nPresenter:  \nJohn Montesano\nAssociate Professor\nUniversity of Waterloo \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:CKN’s Approach to Developing Products with Composite Materials
DESCRIPTION:There are many approaches used to develop products. Products made from composite materials\, however\, are unique in that processing has a great effect on the outcome. This webinar will introduce the Knowledge in Practice Centre’s (KPC’s) approach to composite product development. \nThe development process for composites is an iterative cycle that requires careful consideration of MSTEP (Material\, Shape\, Tooling\, Equipment and Process) throughout. The three main stages for the development of products composed of composite materials include selecting the requirements for the design\, defining the material and shape\, and identifying the process steps. The functional requirements are set as the first step of development and guide the direction of the following steps. The material and shape are considered in regards to the functional requirements\, and influence each other during the selection process. Finally\, the process steps and methods need to be identified with regards to the material and shape\, and the available equipment and tooling. \nThis webinar will provide a guide to navigate the complex nature of composite material part development and point to resources within the KPC to further support your needs. \nPresenter:\nDr. Casey Keulen\nDirector\, Knowledge in Practice Centre\nAssistant Professor of Teaching\, Department of Materials Engineering\, UBC\nCo-Director\, Master of Engineering Leadership\, AMM Program\, UBC \nThis webinar is co-hosted by Composites Knowledge Network (CKN) and SAMPE Canada

SUMMARY:Introduction to the welding of thermoplastic composites
DESCRIPTION:When fabricating a composite structure\, subcomponents need to be assembled. For conventional thermoset composites\, this is done using adhesive bonding or mechanical fastening. In the case of thermoplastic composites\, welding\, also called fusion bonding\, can be used as a joining method. Welding offers several advantages over the other joining methods as it is a fast process that does not require drilling holes in the parts. It consists in bringing together two thermoplastic composite parts and heating their interface above the polymer glass transition or melting temperature. The joining interface is then cooled down under pressure\, resulting in a welded joint. \nThis talk will introduce the fundamental mechanisms responsible for adhesion in any welding process. A review of various welding processes will then be presented with special focus on resistance\, induction and ultrasonic welding. Finally\, joints quality characterization methods will be discussed\, and general welding guidelines will be provided. \nThis presentation is part of CKN’s ongoing Application + Impact (AIM) webinar series.

SUMMARY:Heat Transfer in Composites Processing
DESCRIPTION:Heat transfer during composites processing is an important mechanism to understand as it greatly influences the thermal history and in turn outcome (material properties) of a composite part. It is important to understand that the temperature setting on the equipment is not necessarily the temperature that the part sees. \nIn this webinar we will look at heat transfer mechanisms during processing in more detail. Theory\, simulation\, and experimental results will be used to describe and explain the concepts. Specific cure environments commonly used in industry will be broken down into basic models\, with key parameters highlighted and discussed in more detail. Information on analyzing various processes to successfully cure composites will be presented. \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Effect of cure on mechanical properties of a composite (Part 2 of 2)
DESCRIPTION:The motivation to achieve a ‘proper cure’ seems obvious/intuitive but what really happens if we don’t cure a thermoset composite properly? How does the degree of cure affect the mechanical properties of the material? How does the degree of cure affect the material’s ability to stand up to ‘hot’ conditions and/or ‘wet’ conditions? \nIn the second part of this two-part webinar series\, we will extend what was done in the first part to look at the effect on specimens that have been conditioned in moisture (‘wet’ condition) and tested at both ambient temperatures and elevated temperatures (‘hot’ condition)\, commonly referred to as ‘hot-wet’ conditions. \nIn the first of this two-part webinar series\, we discussed thermal management of the curing process and identified potential situations where a composite may be under-cured or thermally degraded (exposed to excessive temperature during cure). We looked at the results of over 125 mechanical tests including tensile\, compression\, in-plane shear (Iosipescu)\, and short-beam shear (interlaminar shear strength) on specimens that have been significantly under cured\, moderately under-cured\, cured according to the manufacturer’s recommended cure cycle\, and thermally degraded to identify the effect this has on mechanical properties.

SUMMARY:Fabric Forming: how it affects design and processing\, and how simulation can address this
DESCRIPTION:One unique benefit that composite materials have is the ability to be formed into complex geometries that other materials struggle with. Forming fabric into these geometries is key to producing these geometries. \nIf the wrong fabric is used for a particular geometry and/or process it can lead to defects\, such as severe fibre distortion\, porosity\, reduced fibre volume fraction\, and undesirable part thicknesses. In a worst-case scenario\, it could lead to scrapping tooling and materials\, and going back to the beginning of the design/material selection process. \nIn this webinar\, we will discuss how forming fibre material into a shape effects part design\, material selection\, and processing. We will introduce forming testing and simulation and discuss how it can be used in common applications with attention to fabric wrinkling defects. \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Fibre Architecture: Availability\, pros and cons\, and selection for my application
DESCRIPTION:Selecting the form of fibre\, often referred to as the fibre architecture is a critical decision during the development process. Fibre architecture has a significant effect on cost\, processability\, defect generation\, design/geometry limitations\, damage tolerance\, and other outcomes of a composite part. \nIndividual fibres are grouped into bundles of thousands of fibres called tows. These tows then go through a secondary process to create a material form that is then used to produce a composite part. This fibre architecture may be in the form of a unidirectional fabric\, woven fabric\, non-crimp fabric\, braided tube/sleeve or mat\, among others. \nIn this webinar\, we will discuss common types of fibre architecture\, their pros and cons\, suitability to specific processes\, and provide insight on how to select a fibre architecture for your application. \nThis presentation is part of the ongoing CKN webinar series.

SUMMARY:Understanding polyester resin processing: the effect of ambient temperature on final part cure
DESCRIPTION:Controlling the curing parameters of resin\, often referred to as thermal management\, has a significant effect on the outcome of a thermoset polyester resin and therefore the overall performance of a composite part. \nAllowing polyester resin to cure under ambient conditions is the most common technique used in industry. One major drawback of this technique\, however\, is the lack of control over temperature during the process. Often parts are cured in a facility with little temperature control leaving them susceptible to temperature variation throughout the day\, week\, month\, and year. For example\, the outcome of a composite part cured at room temperature in the winter may be different from a part cured in the summer. \nIn this webinar we will show the effect of ambient temperature on the cure of a polyester resin through experiment and simulation\, discuss how this can affect the part\, and present techniques to control it. \nInstructor:\nDr. Casey Keulen\nDirector\, Knowledge in Practice Centre\nAssistant Professor of Teaching\, Department of Materials Engineering\, UBC\nCo-Director\, Master of Engineering Leadership\, AMM Program\, UBC \nRegister here

SUMMARY:Composites Process Simulation: A Review of the State of the Art for Product Development
DESCRIPTION:A fundamental concept in materials science is that process history leads to microstructure evolution\, which in turn determines mechanical and functional properties. For composite components\, where the material is transformed at the same time as the component is created\, the local process history is a function of the whole processing system which includes material(s)\, part shape\, tooling\, and equipment. \nAs both structural size and production scale up\, controlling process history and hence microstructural and property evolution becomes progressively more difficult.  In an ideal situation\, every step of the process is well understood in terms of the underlying physics and can be simulated mathematically.  The quality and breadth of\, and confidence in these process simulations determines how they can be used. If low\, they can be used as job-aids which are validated experimentally. If high\, they might be used as part of the formal process validation and documentation. \nDeveloping this type of capability is the current rage across all manufacturing industries\, under the banner of Integrated Computational Materials Engineering (ICME)\, Industry 4.0\, and the like.  However\, composites manufacturing processes are very complex\, and there is a notable lack of data compared to other industrial sectors with much larger production volumes. \nAlthough adoption of these new technologies has been slower than elsewhere\, the last twenty years are showing accelerating adoption of process simulation in the aerospace composites sector. This webinar introduces process simulation\, with a high-level assessment of the state of the art\, and guidance on how it might be used as part of a product development approach. \nPresenter: \nDr. Anoush Poursartip\nDirector\, Composites Research Network\nProfessor\, Department of Materials Engineering\, UBC\nDirector of Research\, Convergent Manufacturing Technologies \nRegister here

SUMMARY:Resin Behaviour During Processing: What are the key resin properties to consider when developing a manufacturing process?
DESCRIPTION:During manufacturing the resin undergoes significant transformations: thermoset resins evolve from a low molecular weight liquid to a highly cross-linked solid. A thorough understanding of this liquid-to-solid transition is critical when developing\, optimizing or troubleshooting a manufacturing process. For example\, the impregnation and consolidation of the fiber bed must be completed before the resin transforms from a viscous liquid to a rubbery gel\, and demolding must happen when the resin reaches a glassy solid state. \nThis webinar will discuss the key manufacturing properties of thermoset resins such as viscosity\, gelation\, glass transition temperature\, and degree of cure. Short videos will be used to demonstrate the different techniques used today to characterize these manufacturing properties. The content of this webinar will be extracted live from the Knowledge in Practice Centre (KPC) – an open resource for composites manufacturing knowledge and best practices\, available online at https://compositeskn.org/knowledge-in-practice-centre/. \n  \nPresenter:\nDr. Christophe Mobuchon\nResearch Engineer\, Composites Research Network \nRegister here
