IN VI TRO DEGRADATION CHARACTERISTIC OF CARBON FIBERREINFORCED POLYLACTIDE ( C/ PLA) COMPOSITE

Carbon fiber-reinforced polylactide (C/ PLA) composite used for bone fracture fixation was prepared ,and the change of mechanical performance was investigated during in vi t ro degradation. The result indicates that themechanical performance of C/ PLA composite descends to some extent , however , the C/ PLA composite whose carbon fiber was t reated by the surface soakage with thick nit ric acid attains a slow degradation rate , which denotes thatthe st ronger interfacial bonding st rength can rest rain in vi t ro degradation of C/ PLA composite.
