The impact of the size distribution of the reinforced particles on the mechanical properties of composite materials is studied, according to the corresponding parameters, the finite element model of the composites on the model of Al based SiC composites is established. With the method of finite element simulation, the surface displacement and stress distribution of particle reinforced composites whose surface is pressed by a line uniformly load is solved, the effects of reinforced particles buried depth, length to diameter ratio, the young’s modulus ratio of matrix and particles, and rotation angle on the mechanical properties of composites are also analyzed The article outlines concrete influences of the structure parameters and spatial distribution parameters of particles which distribute in the composites on the surface displacement and stress distribution of the composites.
