Abstract

The elastic Young's modulus and shear modulus of bone-particle impregnated polymethylmethacrylate (PMMA) has been measured experimentally at room temperature as a function of bone particle concentration. It was found that the moduli increased with increasing bone particle content. This increase was less than the stiffness increase predicted by higher-order composite theory [1, 2] under the assumption of perfect bonding between particles and matrix. It was concluded that a bond existed but that it was not a perfect bond.

摘要

在室温下，对骨颗粒浸渍聚甲基丙烯酸甲酯（PMMA）的弹性杨氏模量和剪切模量进行了实验测量，测量结果是骨颗粒浓度的函数。结果发现，模量随骨颗粒含量的增加而增加。在假设颗粒与基体之间完美结合的情况下，这种增加小于高阶复合材料理论[1,2]预测的刚度增加。得出的结论是，两者之间存在结合，但并非完美结合。
