| 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 vitro degradation. The result indicates that the mechanical performance of C/PLA composite descends to some extent, however, the C/PLA composite whose carbon fiber was treated by the surface soakage with thick nitric acid attains a slow degradation rate, which denotes that the stronger interfacial bonding strength can restrain in vitro degradation of C/PLA composite. |

| Keywords: | carbon fiber C/PLA composite degradation in vitro mechanical performance |
