Welcome to the CKN Knowledge in Practice Centre!

The Knowledge in Practice Centre (KPC) is one pillar of the Composites Knowledge Network's mandate to assist Canadian enterprise with composite materials so that we can grow the industry and the economy together. Before introducing you to the Knowledge in Practice Centre, let's first get you familiar with the Composites Knowledge Network.

The Composites Knowledge Network (CKN)[edit source]

The Composites Knowledge Network is a non-profit organization that is a Knowledge Mobilization Initiative Network under the Canadian Government's Networks of Centres of Excellence (NCE) program.

Vision Statement[edit source]

The vision of the Composites Knowledge Network is to be Canada’s authority in translating world-class knowledge on composite materials and structures to industry quickly and effectively to benefit small businesses, their employees, and the communities they serve.

Goals of the Composites Knowledge Network[edit source]

The Composites Knowledge Network's goals are to:

  1. Reduce the barriers Canadian businesses face in accessing leading-edge composites manufacturing knowledge
  2. Intensify the uptake of composites technologies in new sectors
  3. Increase the domestic visibility of composites innovation in real time
  4. Intensify Canadian skills mobilization and job creation
  5. Build and strengthen collaborations with and between knowledge users
  6. Increase collaboration across disciplines and sectors, with particular impact in marine, industrial, sports and recreation, infrastructure, and the aerospace and automotive industries
  7. Help Canadian businesses increase revenues and by extension grow the economy
  8. Boost the international visibility of Canadian composites expertise
  9. Unite a cohesive, collaborative and synergistic Canadian composites industry
  10. Help make Canada a world leader in advanced composites manufacturing

Pillars of the Composites Knowledge Network[edit source]

The Composites Knowledge Network will complete its goals through four main avenues (or pillars) of activity:

  1. The Knowledge in Practice Centre
    • You're here right now! This is the place to come for practical guidance on analyzing all aspects of designing and manufacturing composite parts
  2. Application + Impact Mobilization Events (AIM Events)
    • Through AIM events CKN interacts directly with you - the knowledge user - to provide science-based training in all aspects of composite part development. By utilizing the KPC during these events, we'll guide users through the content so that they can improve their understanding of how the content of the KPC can be integrated into their own work.
    • Initially planned to be a series of in-person training events accross Canada, these events have now been moved online to facilitate distancing and even greater outreach.
  3. Canadian Composites Alliance (CCA)
    • Colloquially the "CKN Concierge Service", the CCA aims to give Canadian SME's an edge over international competition by providing individualized and direct support to get them the equipment, resources and expertise they need locally.
    • By building an alliance of Canadian composites SME's with a wealth of products, equipment, services and expertise, the Canadian Composites Alliance is a way of integrating our industry nationwide. This enables us to enhance our effectiveness and promote collaboration and utilization of Canadian business to grow the industry in Canada.
    • We're still working on the framework for the CCA, but if you would like support in the interim, please contact us!
  4. Composites Communications
    • Our newsletters, emails and social media posts on Twitter and LinkedIn will keep you informed about new content in the KPC, upcoming AIM events that you can attend, and information on the Canadian Composites Alliance

The Knowledge in Practice Centre[edit source]

The Knowledge in Practice Centre is the cornerstone of the Composites Knowledge Network. It houses resources for all levels of the composites industry; from people learning about composites, to experienced manufacturers looking to update their processes and methods. It is a repository of state-of-the-art composites knowledge and best practices with a focus on providing Canadian industry with the information it needs to effectively analyze design decisions. With this knowledge, Canadian companies will be better equipped to produce the best composite parts at low cost (improve margins to generate growth) and highest quality (building growth by reputation) while meeting market demands for production volumes (supply) and functionality.

The Knowledge in Practice Centre does this through text, images and figures, videos and oral history formats. By curating the content in the Knowledge in Practice Centre and providing references to important literature (textbooks, standards, trade magazines, technical manuals, academic journals and theses about composite materials), our aim is to give our knowledge users the information they need to make effective and efficient choices for theirn products and their factories.

Building Blocks of the KPC[edit source]

The KPC is broken out into the following 6 areas or volumes:

  • Introduction: This area provides an introduction to composite materials and composites manufacturing processes with an emphasis on understanding the link between designing and manufacturing with composites
    • Articles: Introduce key concepts around composite materials and processes while highlighting the concepts and importance behind the systems approach needed to analyze composite materials effectively by considering equipment, tooling & consumables, part geometry and material simultaneously
  • Foundational Knowledge: This area contains information about the fundamentals and underlying science of designing and manufacturing composite parts
    • Articles: Introduce the fundamental science and parameters that influence the outcomes of composite part manufacturing
    • Methods: Provide information on how to measure or analyze parameters that will affect the system response
    • Worked examples: Provide completed examples of applying the methods
  • Systems Knowledge: A practical look at the systems approach required for analyzing and manufacturing composites; this area focuses on how the equipment, tooling & consumables, part geometry and materials (collectively, system objects) interact to achieve desired outcomes; and how to manage, optimize and control the system
    • Articles: Introduce and expand on how the system objects interact during processing to affect the outcomes of manufacturing
    • Methods: Provide information on how to measure or analyze systems interactions and their outcomes
    • Worked examples: Provide completed examples of applying the methods
  • Systems Catalogue: This area provides details on the system objects that interact during processing (equipment, tooling and consumables, part geometry and material)
    • Articles outline all the objects (equipment, tooling & consumables, part geometry & material) relevant to composite materials and their processing
  • Practice: Putting the knowledge into practice, this area houses science-based guidance to support decision-making processes for new product development, building up composite factory capabilities and optimizing or troubleshooting existing composite factories.
    • Practice documents provide guidance by summarizing how to combine foundational knowledge, systems knowledge and their relevent methods to tackle challenges that engineers face in their everyday work with composites
  • Case Studies: This area houses real-life case studies and shows how the content in the Practice volume has been leveraged to solve real-world problems
    • Case studies examine real-world examples of applying the guidance provided in the practice documents so that engineers can better understand how to apply the that guidance. The case studies also provide a view into the common challenges facing industry and the ways in which they have solved them.
  • Perspectives: This area contains a mixture of media forms and external links to provide context and insight to help knowledge users gain perspective and apply the guidance provided by the KPC

Welcome

Welcome to the CKN Knowledge in Practice Centre (KPC). The KPC is a resource for learning and applying scientific knowledge to the practice of composites manufacturing. As you navigate around the KPC, refer back to the information on this right-hand pane as a resource for understanding the intricacies of composites processing and why the KPC is laid out in the way that it is. The following video explains the KPC approach:

Understanding Composites Processing

The Knowledge in Practice Centre (KPC) is centered around a structured method of thinking about composite material manufacturing. From the top down, the heirarchy consists of:

The way that the material, shape, tooling & consumables and equipment (abbreviated as MSTE) interact with each other during a process step is critical to the outcome of the manufacturing step, and ultimately critical to the quality of the finished part. The interactions between MSTE during a process step can be numerous and complex, but the Knowledge in Practice Centre aims to make you aware of these interactions, understand how one parameter affects another, and understand how to analyze the problem using a systems based approach. Using this approach, the factory can then be developed with a complete understanding and control of all interactions.

Interrelationship of Function, Shape, Material & Process

Design for manufacturing is critical to ensuring the producibility of a part. Trouble arises when it is considered too late or not at all in the design process. Conversely, process design (controlling the interactions between shape, material, tooling & consumables and equipment to achieve a desired outcome) must always consider the shape and material of the part. Ashby has developed and popularized the approach linking design (function) to the choice of material and shape, which influence the process selected and vice versa, as shown below:

The relationship between function, material, shape and process


Within the Knowledge in Practice Centre the same methodology is applied but the process is more fully defined by also explicitly calling out the equipment and tooling & consumables. Note that in common usage, a process which consists of many steps can be arbitrarily defined by just one step, e.g. "spray-up". Though convenient, this can be misleading.

Workflows

The KPC's Practice and Case Study volumes consist of three types of workflows:

  • Development - Analyzing the interactions between MSTE in the process steps to make decisions on processing parameters and understanding how the process steps and factory cells fit within the factory.
  • Troubleshooting - Guiding you to possible causes of processing issues affecting either cost, rate or quality and directing you to the most appropriate development workflow to improve the process
  • Optimization - An expansion on the development workflows where a larger number of options are considered to achieve the best mixture of cost, rate & quality for your application.
