复合材料的热膨胀率,关系到复合材料结构的尺寸稳定性和热应力,是复合材料的一个重要性能指标,根据复合材料的组分性能及其细观结构预测其热胀系数和热失配应力,是复合材料结构分析和设计中所关心的。这方面已经有了相当数量的研究工作,如石连升等人[1]研究了单 The thermal expansion coefficient of the composite material is related to the dimensional stability and thermal stress of the composite structure. It is an important performance index of the composite material. The thermal expansion coefficient and the thermal mismatch stress of the composite material are predicted according to the component properties and the mesostructure of the composite material , Is the composite structure analysis and design of the concern. There have been a considerable number of research work in this area, such as Shi Lian Sheng et al [1] studied a single
