摘要
以碳纤维为增强材料对具有较高孔隙率的骨水泥进行补强,利用FTIR、SEM和EDS对骨水泥的显微结构和碳纤维表面晶体组分进行了观察和分析。试验结果表明,硝酸氧化处理提高了骨水泥对碳纤维的浸润性和碳纤维的表面化学活性,增加了界面粘结性能,改善了骨水泥和碳纤维之间的界面结合。
In this study, the bone-cement with high porosity is strengthened by carbon fibers as reinforce materials. The crystalline composition of carbon fibers＇ surface and microstructure of the porous bone-cement were investigated by FTIR,SEM and EDS respectively. The results indicate that Nitric acid oxidation not only enhances the infiltration and the activity of carbon fibers＇ surface, but also improves the interracial bonding property, which improve the combination of interface between porous bone-cement and carbon fibers.
