APPLICATION OF GAS LIQUID PHASES DOUBLE EFFECTIVENESS SURFACE TRETAMENT METHOD

Carbon fibers reinforced plastics composites(CFRP) is a main form of utilization of carbon fibers. Practically the mechanical performance of CFRP made of untreated rayon based carbon fiber (RCF) is lower. After surface treatment of gas liquid phases double effectiveness method, the mechanical performance of CFRP made of treated RCF was improved largely. Synchronously tensile strength and elongation at break of treated RCF were also increased. This surface treatment method of carbon fibers has been applied in the production line of carbon fibers.
