Predictions of the Effective Elasto-Plastic Properties and Cohesive Strength of the Spruce Fiber Reinforced Polypropylene Composite

Abstract:

The spruce fiber reinforced thermoplastic polypropylene (PP) composite is studied in this paper aiming at inspecting the effect of micromechanics parameters on the effective elasto-plastic property of composite by the numerical methods. The local stress field changing with the fiber aspect ratio and volume fraction is detailed investigated. At the last the normal cohesive strength of the interface is predicted initially. The numerical results show good agreement with the theoretical prediction results and available data.
