摘要
通过微分方法研究了复合泡沫塑料的有效模量性质．结果表明：这一方法可预测较高空心球体积含量复合材料的模量，对其结果进行修正后，可正确预测复合泡沫塑料的杨氏模量。
The effective elastic modulus of the composite containing hollow spheres is investigated by differential scheme. The results what we have derived show that the moduli of the composite with higher volume fraction of hollow spheres can be predicted by this method. The modified result of Young's modulus can be used to predict the Young's modulus of the syntactic foam plastics in which some voids are included. A quite good agreement has been obtained between the experimental results and prediction of the theoretical Young's moduli.
