Analysis of Elastic Properties According to the Aspect Ratio of UHMWPE Fibers Added to PP/UHMWPE Composites

This study comparatively analyzed the behavior of elastic properties by aspect ratio ultra-high molecular weight polyethylene (UHMWPE) fibers that are added when creating a composite material polypropylene and UHMWPE. The volume fraction (VF) UHMWPE to was fixed at 5%. were lumped for analysis according oriented on matrix; they using Halpin–Tsai model, which involves theoretical approach finite element based homogenization method. Finite performed fiber ratios 0.2 30 via technique ANSYS Material Designer. For comparison, 100 model. When 0.2, it calculated as 1518 MPa, 30, 2365 increased 55.8%. As increased, E22 G12 converged constant value (1550 MPa). In future, changes from 0 50%, must be conducted analyze predicted changes.
