Abstract

A 3-D simulation of interfacial stress distribution between particulate and matrix during tension of a polypropylene/calcium carbonate is made by means of a finite element method with ANSYS. The results show that the shear stress increases with increasing the angle from the equator of the particle (α) and reaches maximum around 20°. The tensile stress at Y direction increases with increasing α then slightly varies when α is more than 50°. The tensile stress at X direction decreases with increasing α and reaches the minimum around 35°. The stress distribution of 3-D model is gentler than that of 2-D model.
