Teijin Limited announced today that it has developed a thermosetting, long carbon fiber-reinforced plastic (CFRP) that combines a heat-activated self-healing function with high recyclability, while offering mechanical properties equivalent to those of conventional CFRPs. Damaged areas of the new material can be repaired by being heated for a short time at a specified temperature, enabling repair rather than replacement and thereby helping to extend product lifetime and reduce resource consumption. Further, Teijin’s CFRP enables recycling through a simple chemical decomposition process, thereby contributing to circularity. A wide range of applications can benefit from the strength and light weight of this CFRP material, including aircraft, automobiles and sporting goods. There is growing demand for products that help to reduce greenhouse gas (GHG) emissions throughout the entire life cycle. However, CFRPs, made by impregnating carbon fiber with thermosetting resin, cannot be melted or r...
