| 摘 要： | 利用层状球形夹杂在无限大基体中的局部化关系及平均应力场理论,给出了一种方法来分析含 n 种层状球形夹杂所构成复合材料的弹性模量.对于文献给出的空心玻璃球和高分子基构成的复合材料,该理论的预测与实验吻合很好.当表层稍失时,该理论退化为传统的 Mori-Tanaka平均应力场理论.

| Abstract: | A model is proposed to evaluate the,effective modufi of a composite reinforced by two-layered spherical inclusions.This model is based on the localisation problem of a two- layered spherical inclusion embedded in an infinite matrix.The interations of the reinforced phases are taken into account by using the average matrix stress concept.When the external layer vanishes,the proposed model reduces to the classical Mori-Tanaka's model for spherical inclusions.Theoretical results for the composite of polyester matrix filled by hollow glass spheres and voids show excellent agreement with experimental results. |
