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 和SEM对碳纤维表面晶体组分和骨水泥的显微结构进行了观察和分析,并对骨水泥的力学强度进行了测试.试验结果表明,硝酸氧化处理改善了骨水泥和碳纤维之间的界面结合,碳纤维的长度和添加量都会对骨水泥的力学强度造成影响.同时,碳纤维"井"字形添加工艺也能起到增强骨水泥的作用.
以碳纖維為增彊材料對具有較高孔隙率的骨水泥進行補彊,利用FTIR 和SEM對碳纖維錶麵晶體組分和骨水泥的顯微結構進行瞭觀察和分析,併對骨水泥的力學彊度進行瞭測試.試驗結果錶明,硝痠氧化處理改善瞭骨水泥和碳纖維之間的界麵結閤,碳纖維的長度和添加量都會對骨水泥的力學彊度造成影響.同時,碳纖維"井"字形添加工藝也能起到增彊骨水泥的作用.

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 and SEM.And mechanical strengths were tested as well.The results indicate that Nitric acid oxidation not only enhances the infiltration and the activity of carbon fibers' surface,but also improves the interfacial bonding property,which improve the combination of interface between porous bone-cement and carbon fibers.Meanwhile,the strength tests show that both the length and the contents of carbon fiber could have effects on bone-cement mechanical strength respectively.Finally,the tic-tac structure system of carbon fibers could enhance the strength of bone cement.
