This section of the KPC contains a collection of public presentation recordings on a variety of topics related to composites. The content largely includes one person giving a presentation on a single subject to an audience (in-person and digitally), often with question and answer periods at the end. Click here to explore the presentations.

Have you ever wanted to have a one-on-one conversation with a composites expert? While we haven't figured out how to clone them and accomplish that, we are reaching out to our extensive contact list of researchers and industry experts to bring you these interviews with a more relaxed format than a public presentation. By giving our interviewees the freedom to discuss the topics they find the most interesting and important - rather than being restricted to a presentation on a single topic - we think you'll find the content here both intriguing and thought provoking. Click here to explore the interviews.

This section of the KPC contains the Application and Impact Mobilization (AIM) events. 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 understanding of the intricacies of composite materials design, analysis and manufacturing, and be better equipped to address them in their own parts.

Overview[edit | edit source]

When manufacturing anything, the importance of know-how can often eclipse the value of know-why in the short term because it is often the fastest way to achieving a desired end-goal. The consultancy industry's very premise is offering know-how with a minimum of lead time in order to improve time-to-market for new product development, reduce manufacturing time & cost for process optimization or improve quality for underperforming processes. Know-how has immediate value and the perspectives volume aims to bring as much know-how to you by curating a mixture of unstructured (online videos, interviews) and structured (AIM event) resources that provide additional insight and perspective on composites research, design and manufacturing.

We believe it is important to capture, protect and convey as much know-how as possible because it is the first step in transforming manufacturing processes. The protect-advance-disrupt construct [1] put forward by Fabris advocates the improvement and advancement of manufacturing processes by not losing sight of the know-how that brought us to where we are today. By first protecting the hard-earned know-how and then advancing it with know-why, advances in manufacturing processes can be made that have the ability to disrupt the current status quo.

How to use this volume[edit | edit source]

Volume Framework[edit | edit source]

Practicing your foundational knowledge with all the complexities of the systems interactions taking place while trying to make reasonable practical decisions is always challenging. Through the videos and other content in this volume, some perspective of how to apply knowledge in practice is conveyed. We hope that by providing some external perspective and examples in this volume that you will be more comfortable in how to apply these concepts to your work.

Volume Features[edit | edit source]

Most pages in the perspectives volume consist of a video as the primary focus. Video from CKN are embedded within the KPC page itself, whereas videos from others are linked out to.

It is CKN's goal to index the content of our videos so that you can quickly find content of interest to you. For each indexed chapter that relates to other content within the KPC, links will be provided so that you may improve your understanding of what is discussed in the video and relate it to the method and practice documents. You will find this index below the video in the "Additional information for select chapters" section. For videos posted by CKN and videos by others with chapter markers, the index is provided by chapter numbers that correspond to the chapter markers integrated into the video player. For non-CKN videos without chapter markers, the index is provided by timestamp.

Interviews[edit | edit source]

Interview Icon-JJBnrDwmVS9r.svg
The Composites Knowledge Network is working towards recording and curating a number of interviews with notable subject matter experts within the composites engineering community. The primary objective is to facilitate as much open knowledge transfer as possible, particularly in areas of tribal or tacit knowledge - which is often best conveyed through direct interaction with someone having first-hand experience. The section on interviews contains these often one-on-one conversations to bring you interesting ideas and concepts directly from those with the experience. Click here to explore the interviews.

If you have an informed, unique perspective that you believe would benefit the composites community, please contact us to discuss the opportunity for your very own interview to be featured in the Knowledge in Practice Centre.

AIM Event Recordings[edit | edit source]

AIM Event Icon-JJBnrDwmVS9r.svg

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.
