Application

Design takeaway

How to apply

When designing new composite products, explicitly consider the materials' recyclability. Research and select fibers and resins that are amenable to existing or emerging recycling technologies. Incorporate design features that simplify disassembly, such as using fewer adhesive bonds or standardized fasteners.

Project actions

01When choosing materials for your design, research their end-of-life options and recyclability.
02Consider how your design can be taken apart easily for repair or recycling.

Think critically

While recycling rates are high, what are the implications of potential fiber degradation during the recycling process on the performance of recycled composites, and how can this be addressed in design?

Design Principles

"Design for Circularity: Prioritize material selection, modularity, and ease of disassembly to enable efficient recycling and reuse of composite materials throughout their lifecycle."

As industries like aerospace and automotive increasingly rely on high-performance composites, adopting circular approaches is crucial for mitigating resource depletion and waste. This research provides a framework for designing, manufacturing, and managing composites to maximize their lifecycle value.

What This Means for Your Design

We can reuse a lot of the materials in strong, light composites by breaking them down and recycling the fibers, which is better for the planet.

How to use in your project

1.Use this research to justify material choices based on their environmental impact and recyclability.
2.Incorporate design-for-disassembly principles into your design process and explain how they contribute to circularity.
