Numerical Simulation of Tensile Behaviors for Random Spruce Short Fiber Reinforced Composites

Article Preview

Abstract:

Natural short fiber reinforced composite is promising in motor industry, it is meaningful to study the tensile property of spruce short fiber reinforced polypropylene (PP) composite. In this paper, the finite element model is developed with the consideration of the fiber random orientation, random distribution, fiber volume content and interphase effect, especially the cohesive zone model to simulate the interphase property. The tensile behaviors of the short spruce/PP composite with kinds of fiber volume content are predicted. The results show that both strength or stiffness and experimental data are well identical.
