By combining molecular design and structural analysis supported by universities and proprietary nano alloy technology owned by Toray, a research team at the company succeeded in uniformly dispersing a polyrotaxane circular polymers in the matrix resin of CFRP at the nanoscale. While maintaining the high strength and rigidity of CFRP, the new material was about 3fold more fatigue-resistant. With this technology, carbon fiber reinforced plastic is expected to be expanded to new fields including aircraft, automobile, sporting goods, medical care and the like over the next 10 years.
