横向压缩载荷下短纤维复合材料细观力学分析
Micromechanics analysis of short fiber-reinforced composites under transverse compressive loads
摘要
Abstract
A micromechanics model, including fiber, interface and matrix of fiber-reinforced elastomer matrix composites subjected to transverse compressive loads, was established, and the function of the stress distribution in the fiber and the matrix was obtained. Moreover, the regularity of the stress distribution in two different fiber reinforced elastomer matrix composites was investigated by the single fiber model. Results indicated that the stress distribution in the unit cell was inhomogeneous depended on the fiber volume fraction and the inhomogeneity of the composites. The inhomogeneity of the stress distribution increased with the increase of the inhomogeneity of the composites. With the fiber volume fraction increased , the maximum value of the compressive stress increased gradually, while the maximum value of the tensile stress increased first and then decreased gradually.关键词
