Young's modulus and Poisson's ratio have been measured simultaneously on a series of particulate composites containing volume fractions of filler up to 0.50. The composites consisted of small glass spheres imbedded in a rigid epoxy polymer matrix. The measured values were compared with theoretical values calculated from current theories. A recently generalized and simplified version of van der Poel's theory provided the best agreement. It predicted values of Young's modulus for composites with filler volume fractions up to 0.35. Measured values of Poisson's ratio exhibited scattering, but were consistent with values calculated from van der Poel's theory.
已对一系列填充体积分数高达0.50的颗粒复合材料同时测量了杨氏模量和泊松比。这些复合材料由嵌入刚性环氧聚合物基体中的小玻璃球组成。将测量值与根据现有理论计算出的理论值进行了比较。范德波尔理论最近的一个广义简化版本给出了最佳拟合。它预测了填充体积分数高达0.35的复合材料的杨氏模量值。泊松比的测量值存在散射，但与根据范德波尔理论计算出的值一致。
