The Effect of Micromechanics Models: 2D and 3D Numerical Modeling for Predicting the Mechanical Properties of PP/Alfa Short Fiber Composites

In the present work, we propose to confront two modeling techniques for predicting macroscopic properties of short alfa fiber-reinforced polypropylene composites. The first was a micromechanical analysis using Mori-Tanaka, Self-consistent, Diluted, Voigt, Reuss, and Neerfeld-Hill models. second digital, specific finite element technique called Projected Fiber (PF) approach. framework this study, both 2D 3D analyses based on PF approach were used. First, proposed an inverse these analytical models predict Young’s modulus fiber. Then, compared obtained results with experiment values available in literature. This comparison showed that underestimated fiber’s modulus, while approach, PF, allowed good framing experimental values. Moreover, investigated effect fiber content predicted elastic (PP) matrix reinforced randomly distributed fibers. We noticed Diluted model more accurate than Mori-Tanaka Self-consistent methods. As its estimations close For example, PP/alfa 30 wt% error 4.3%. It is shown can provide calculated sufficient prediction accuracy.
