Abstract: In this work, the stress distribution in fiber and matrix of polypropylene base composites under axial loading was studied using numerical method. In this method, according to the two-dimensional symmetric, the distribution of stress was studied using ABAQUS software to evaluate the strength of fiber and matrix. Two different reinforcing agents, including carbon and glass fiber, were used separately in a polypropylene matrix in which the volume percent of fiber was varied from 1.5 to 15. The numerical method showed that increasing the fiber volume fraction resulted in a change in stress distribution over fiber Length from parabolic to trapezoidal form. Comparison of theoretical and experimental results showed a good agreement and they were in accordance with literature. It was also shown that numerical method can be used as a quick and easy method for predicting the mechanical behavior of manufactured short-fiber reinforced composites with good accuracy.
