SUMMARY:Effect of cure on mechanical properties of a composite (Part 1 of 2)
DESCRIPTION:The motivation to achieve a ‘proper cure’ seems obvious or 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 first of this two-part webinar series\, we will discuss thermal management of the curing process and identify potential situations where a composite may be under-cured or thermally degraded (exposed to excessive temperature during cure). Then we will look 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. This data will be compared to NCAMP data on the same material as a benchmark. \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. \nThis work was done in collaboration with ZwickRoell and the Technical University of Munich. It will be partially presented by Dr. Hannes Körber\, Industry Manager Composites\, ZwickRoell. \nThis presentation is part of the ongoing CKN webinar series. Content 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. \nPresenters: Dr. Casey Keulen\, Scott Nesbit\, and Dr. Hannes Körber \nThis webinar is co-hosted by Composites Knowledge Network (CKN)\, SAMPE Canada and ZwickRoell

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. Content 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. \nPresenters: Abbas Milani and Casey Keulen \nThis webinar is co-hosted by Composites Knowledge Network (CKN) and SAMPE Canada

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. Content 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. \nPresenter: Casey Keulen \nThis webinar is co-hosted by Composites Knowledge Network (CKN) and SAMPE Canada

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

SUMMARY:Deconstructing composites processing: Why it seems so complex and how to think about it in a structured way
DESCRIPTION:Composite materials come in many different forms\, shapes\, and sizes. While this allows for flexibility in tailoring the design\, it also results in many different possibilities for manufacturing\, which can seem complicated and daunting. However\, despite there being numerous choices for manufacturers\, the complexities often associated with composite material processing can be deconvoluted and approached in a structured way. \nIn this webinar\, we will lay out a structured approach to composite material manufacturing; from thinking about how material flows through a factory to breaking out process steps into their material\, shape\, tooling\, and equipment parameters. This method of thinking is central to the framework for the Knowledge in Practice Centre (KPC) – one of the core pillars of CKN. \nTo watch the webinar\, click here

SUMMARY:Parameters for Structural Analysis of Composites
DESCRIPTION:Structural analysis of composites requires material properties such as elastic and strength values. Physical testing\, handbook/database values\, micromechanics\, and classical lamination theory are all sources of these properties; but when are they valid and what are their advantages\, disadvantages\, hidden challenges and quirks? When you need nine unique values just to define the elastic response of a composite in three dimensions – not to mention failure parameters – the feat of acquiring these values can considerably affect your schedule\, cost\, and stress levels (pun intended). \nIn this virtual application + impact mobilization (AIM) event\, we provide an overview of these sources of material properties and provide a comparison between them so that you can decide what is most appropriate for your project and how to begin. \nTo watch the webinar\, click here

SUMMARY:Costing Composite Parts
DESCRIPTION:Accurately estimating the cost of manufacturing a composite part is essential to the success of small\, medium and large businesses alike; but where should you begin? Many factors such as material and consumable prices\, labour cost\, purchase and maintenance of equipment and tooling\, energy cost\, development cost\, overhead cost as well as production run numbers and rates can affect the total cost of a part. Many of these factors also involve a certain amount of uncertainty. \nIn this virtual application + impact mobilization (AIM) event we outline the key aspects of costing composite parts and draw your attention to aspects of costing that perhaps you haven’t considered before. \nTo watch the webinar\, click here

SUMMARY:Composite Materials Engineering 12-Part Webinar Series
DESCRIPTION:In a time of uncertainty for the Canadian Composites Manufacturing industry\, one thing is certain: knowledgeable and experienced engineers will be needed to facilitate regrowth of the industry. To support this\, the CKN\, in partnership with SAMPE Canada\, is hosting a 12-part webinar series on composite materials engineering. \nThis series is intended for junior to senior engineers that are looking to obtain a solid background in the fundamentals of composites to help make both engineering and business decisions. After completing this series\, participants will have the skills to identity suitable applications for composites\, select materials and processes\, estimate composite mechanical properties\, and identify appropriate testing procedures. \nThe topics will cover a wide range of aspects of polymer matrix composites from both a processing and analysis perspective. It will start with a general introduction to composite materials\, then discussion of constituent materials like fiber and resin\, before going into thermal management of manufacturing processes (curing a resin). With that knowledge established\, various processing methods will be discussed\, with a deeper look into prepreg processing and liquid composite moulding (ie. vacuum infusion\, resin transfer moulding\, etc.). After that\, the focus will be on the mechanics of composites. What is happening on the lamina and laminate levels\, and eventually failure of composites will be covered. The last two sessions will tie the processing sessions and mechanics sessions together with a discussion of testing. \nInstructor: Casey Keulen\, PhD\, PEng\, Instructor of Materials Engineering at the University of British Columbia \nHosted in partnership with SAMPE Canada \n\n\n\n\nYou can view sessions 1-12 here
