AIM Event Recordings - A115
Application and Impact Mobilization (AIM) events are a key pillar of the Composites Knowledge Network's mandate to improve industry's knowledge of important scientific principles that affect composites. AIM events are a mixture of in-person gatherings and online events such as webinars and other recorded sessions that have been prepared to provide a structured delivery of content to anyone with a technical background. By watching these recorded AIM events, you should have a better understand of the intricacies of composite materials design, analysis and manufacturing, and be better equipped to address them in your own parts.
Composite materials engineering webinar series with Dr. Casey Keulen - 2020[edit | edit source]
Prior to the COVID-19 epidemic, the Composites Knowledge Network was planning a cross-country trip to engage knowledge users with a series of in-person workshops on composite materials. Rather than cancel these AIM events, the Composites Knowledge Network, in collaboration with SAMPE Canada, hosted a 12-part webinar series to reach knowledge users throughout Canada and the world. This series is intended for junior to senior engineers that are looking to obtain a solid background in the fundamentals of composites to help make engineering and business decisions. The series aims to provide knowledge users with the skills to identity suitable applications for composites, select materials and processes, estimate composite mechanical properties, and identify appropriate testing procedures.

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 factory
- Factory cells and/or the factory layout
- Process steps (embodied in the factory process flow) consisting 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:
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.
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.
