Smart prepregs for in-situ damage healing and easier recycling of composite structures

With its self-healing, pre-impregnated textiles, Smart prepregs is a bio-inspired solution for extending the lifetime of composite structures.

Although widely used in the aerospace, automotive, wind and sports industries, composite materials tend to become brittle due to their composition.

Since there are few solutions to effectively repair these materials, damaged items often have to be replaced, resulting in wasted material.

To address this problem, CompPair has created a structural composite that can repeatedly heal small damages, reducing repair time from several hours to a few minutes, while being compatible with most current manufacturing processes.

In addition to its self-healing properties, smart prepregs are crack resistant and highly recyclable. By reducing maintenance costs, increasing product life and being recyclable, smart prepregs provide a highly versatile and durable solution for the composites industry.
