选用3种炭基复合材料,分别为采用化学气相沉积(CVD)工艺和CVD/浸渍复合工艺制备的2种C/C复合材料以及采用CVD/熔融渗硅(MSI)工艺制备的C/C-SiC复合材料,通过对比分析3种炭基复合材料与人骨的微观结构和力学性能,研究了所选用的3种炭基复合材料作为新型骨折内固定材料的可行性.结果表明:3种炭基复合材料与人骨均具有纤维增强、多孔基体的微观结构形态.在力学性能方面,3种炭基复合材料的弹性模量与人骨都较为接近,其中C/C-SiC复合材料的力学性能与人骨最为接近,分别为弯曲强度213.0 MPa、剪切强度19.3 MPa、压缩强度228.1 MPa,有望成为理想的接骨板材料.CVD和CVD/浸渍工艺制备的C/C复合材料,弯曲强度分别仅为161.8 MPa和174.6 MPa,低于入骨的弯曲强度,后期可通过改进坯体结构和制备工艺等方法来使其力学性能与入骨相匹配.
