Initiatives Aimed At Improving the Mechanical Properties of Recycled CFRP

Abstract

Carbon Fiber Reinforced Plastics (CFRP) is widely used in the structural components of aircraft. Upon retirement, aircraft generate a large amount of CFRP waste, typically disposed of in landfills as industrial waste. However, for CFRP to become a sustainable industry staple in the future, methods for recycling and reusing it must be established. Domestic and overseas venture companies are actively working on exploring and establishing technologies to extract carbon fibers. However, despite ongoing research, there remains a scarcity of initiatives aimed at recycled carbon fiber (rCF) utilization. To aim for a complete circular economy in the future, it is desirable to ensure sufficient mechanical properties when turning rCF into CFRP. This paper introduces efforts aimed at improving the mechanical properties of rCFRP.
