摘要： 制备了经过氧化处理的碳纤维增强磷酸钙骨水泥(α-tricalcium phosphate cement/tetracalcium phosphate, α-TCP/TTCP), 初步探讨了碳纤维长径比、含量对硬化体抗压、抗折强度的影响. 实验结果表明长径比为375, 添加量为0.3wt%时, 增强效果最为理想, 抗压强度提高了55%(最大为63.46MPa), 抗折强度提高近100%(最大为11.95MPa), 而掺入量太大及长径比太高, 碳纤维因不能均匀分散将限制其性能的发挥. 生物学评价实验结果表明碳纤维增强的骨水泥具有良好的生物相容性.

Abstract: Oxidation-treated carbon fiber was used to reinforce calcium phosphate bone cement (α-TCP/TTCP).
The effect of length-diameter ratio and content of carbon fiber on the compression strength and bending strength of the hardened body was
preliminarily discussed. The results show that the reinforcing effect is optimal when the length-diameter ratio of carbon fiber is 375 and
the addition quantity is 0.3wt%. The compression strength increases to 155% (maximum: 63.46MPa), bending strength increases to 200% (maximum:
11.95MPa), respectively. However, if the addition quantity is too large or the length-diameter ratio is too high, carbon fiber can
not give play to its function fully, because it can not be dispersed uniformly in the hardened body. The biological evaluation indicates that the carbon
fiber reinforced α-TCP/TTCP has good biocompatibility.

Key words: calcium phosphate bone cement, carbon fiber, reinforcing, biocompatibility
