摘要
本文利用Ｅｓｈｅｌｂｙ－Ｍｏｒｉ－Ｔａｎａｋａ法和改进的刚度平均化方法，考虑各种编织参数下纤维与微裂纹的相互作用，理论预报了复合材料的有效热膨胀系数，比较了不同微裂纹密度对热力学性能的影响，为工程设计和材料工艺改进提供了理论指导。
The EshelbyMoriTanaka theory combined with modified Stiffness Averaging Method is used for considering the interaction of fibers and microcracks and predicting the effective thermal expansion coefficients of threedimensional braided composite with pennyshaped cracks. The effects of microcrack density on the thermal mechanical behavior of the material are also studied. The developed method provides theoretical basis for material designers and manufacturers to improve the material behavior.
