EFFECT OF FIBER ORIENTATION ANGLES ON MECHANICAL BEHAVIOR OF CAR BUMPER COMPOSITE

Abstract

The present work focused on the effect of glass fiber orientation that reinforced polymeric matrix in car bumper composite to understand the mechanical behavior of these materials during work conditions. Tensile test and bending test were performed and discussed for (0^o, 30 ^o, 45 ^o, 60 ^o, and 90 ^o) angles of fibers orientation. The finite element method by program (ANSYS V.13 software) was used to study the behavior of these compounds. The results showed that the extension and deflection values were higher at (0^o) and decreased with increasing fiber angle orientation until reached to a lower value at perpendicular state between fibers and applied loads. The study used to improve the mechanical properties of the composite materials depending on the fiber orientation angle.
