摘要

摘要: 制备了碳纤维增强聚乳酸(C/ PLA) 骨折内固定复合材料, 研究了体外降解过程中其力学性能的变化。结果表明: 在体外降解过程中, C/ PLA 复合材料的各项力学性能均有不同程度的下降, 但经过硝酸处理后的C/PLA 复合材料降解速度缓慢, 表明界面结合强度的提高对降解过程起抑制作用。

Abstract: 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.
