摘要/Abstract

摘要： 使用三维绘图软件Pro/E绘制出三维浅交弯联机织复合材料数字化结构模型,借助大型有限元分析软件ANSYS模拟单胞模型承受不同方向压缩载荷作用下的力学性能。探究在不同方向的压缩载荷作用下复合材料单胞模型的应力分布情况,并借此分析复合材料单胞模型的各向性能;以承受X方向压缩载荷的单胞模型为例,分析复合材料中纤维与树脂的受力情况。结果表明:三维机织复合材料受到压缩载荷时,表现出明显的各向异性,表现为X方向压缩性能最好,Z方向压缩性能最差;纤维作为主要承载体,承担较多载荷作用,树脂作为次要承载体,承担较少载荷作用。

Abstract: 3D composite unit-cell model was created by PRO/E 5.0 mapping software. Compressive property of unit-cell model under multipronged compressive loading were simulated with the help of the finite element software ANSYS. The stress distribution of the unit-cell model was investigated and analyzed. Meanwhile, taking the unit-cell model subjected to compressive loading in X direction for example, the stress distribution of fibers and resin matrix was analyzed. The results showed that 3D composite was obviously anisotropic under compressive loading,manifesting as the best compressive property in X direction and the worst compressive property in Z direction. Fibers made the major contribution to subject the compressive loading, while the resin matrix made the minor contribution to subject the compressive loading.

Key words: finite element, 3D woven composite, unit-cell model, compressive property, anisotropy
