摘　　要：　利用Mori＿Tanaka平均应力的概念和Eshelby等效夹杂的原理,研究了含涂层空心球复合泡沫塑料的弹性性质,从理论上导出了这类复合材料的有效模量预测公式·　此外,基于这些理论公式。The elastic properties of syntactic foams with coated hollow spherical inclusions have been studied by means of Mori and Tanaka's concept of average stress in the matrix and Eshelby's equivalent inclusion theories.Some formulae to predict the effective modulus of this material have been derived theoretically.Based on these formulae,the influences of coating parameters such as the thickness and Poisson's ratio on the modulus of the syntactic foams have been discussed at the same time.

关 键 词：Mori-Tanaka模型 有效模量 涂层 复合泡沫塑料
