| 摘 要： | 以短切碳纤维为增强相, 采用原位复合法制备短切碳纤维(Cf)/羟基磷灰石(HA)生物复合材料。为提高材料的界面结合, 对Cf表面进行氧化处理。对纯HA结构、 Cf表面以及复合材料断口形貌分别采用XRD、 FTIR、 SEM进行分析表征; 采用万能试验机对复合材料进行力学性能测试。结果表明: 氧化处理后Cf表面变粗糙, 有羟基羧基官能团出现; Cf质量分数为3%时Cf/HA复合材料相对密度最大, 力学性能最好, 弯曲强度和弯曲模量分别约为130 MPa和36 GPa。Cf/HA复合材料断口SEM照片表明, Cf质量分数低于6%时能够实现在HA基体中的均匀分布。

| Abstract: | A short carbon fiber(Cf) reinforced hydroxyapatite(HA) bio-composite was prepared by in-situ processing.In order to improve the interfacial bonding of Cf/HA bio-composite,Cf surface was modified by oxidation treatment.The pure HA structures,Cf surfaces and fracture surface morphologies of the bio-composite were analyzed using XRD,FTIR and SEM,respectively.The mechanical properties of the Cf/HA were tested by a universal testing machine.The result shows that after oxidation treatment the surface of Cf exhibi... |
