Welcome đồ sộ the CKN Knowledge in Practice Centre (KPC). The KPC is a resource for learning and applying scientific knowledge đồ sộ the practice of composites manufacturing. As you navigate around the KPC, refer back đồ sộ 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 Clip 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:
    • Material
    • Shape
    • Tooling & consumables
    • Equipment

The way that the material, shape, tooling & consumables and equipment (abbreviated as MSTE) interact with each other during a process step is critical đồ sộ the outcome of the manufacturing step, and ultimately critical đồ sộ 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 đồ sộ make you aware of these interactions, understand how one parameter affects another, and understand how đồ sộ 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 đồ sộ 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 đồ sộ achieve a desired outcome) must always consider the shape and material of the part. Ashby has developed and popularized the approach linking design (function) đồ sộ 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 đồ sộ make decisions on processing parameters and understanding how the process steps and factory cells fit within the factory.
  • Troubleshooting - Guiding you đồ sộ possible causes of processing issues affecting either cost, rate or quality and directing you đồ sộ the most appropriate development workflow đồ sộ improve the process
  • Optimization - An expansion on the development workflows where a larger number of options are considered đồ sộ achieve the best mixture of cost, rate & quality for your application.
