评述了分析单向纤维增强复合材料及纺织复合材料宏观等效弹性性能的有代表性的力学模型 ,指出了各力学模型的特点 .针对经典力学模型分析结构复杂的纺织复合材料的力学性能的局限性 ,直接从组分相的本构方程出发 ,分别将应力、应变张量在相间界面分解成互相正交的 2个部分 :面内分量和面外分量 .在理想界面条件下 ,考虑了纤维与基体的相互作用 ,建立了基于理想界面的均匀化方法 .选取CCA模型分析了单向纤维增强复合材料的弹性性能 ,得到了满意的结果 A representative mechanical model for analyzing the macroscopic equivalent elastic properties of unidirectional fiber-reinforced composite materials and textile composites is reviewed, and the characteristics of each mechanical model are pointed out. In view of the limitation of the mechanical properties of complex mechanical composites with classical mechanical models Based on the constitutive equation of component phase, the stress and strain tensor are decomposed into two orthogonal sections, the in-plane component and the out-of-plane component, respectively at the interphase interface. Under ideal interface conditions, And the interaction between the matrix and the matrix, the homogenization method based on the ideal interface was established.Selected the CCA model to analyze the elastic properties of unidirectional fiber-reinforced composites, and obtained satisfactory results
