Failure Analysis of Hybrid Glass Reinforced Composites in Polymeric Industries

Abstract

This research deals with the failure analysis of hybrid glass reinforced composites in polymeric industries. In this research, fourteen specimens with different compositions were developed. The produced test specimens had a dimension of 210mm length, 150mm width and 50mm thickness which were in accordanc--e with American Society for Testing and Materials (ASTM). The fourteen test specimens produced were subjected to impact test. The critical stress, shear stress and stress distribution for mode I and mode II were investigated and results were obtained. The results obtained shows that specimen A had an optimum critical and shear stress of 9.32 MPa and 25.1 MPa for mode I while specimen C had an optimum critical and shear stress of 2.49 MPa and 7.03 MPa for mode II respectively. It was also observed that specimen I which contained 12 plies of soft mat reinforcement required the least stress magnitude to grow the crack, while specimen C which contained 2 plies of woven roving and one ply of hat mat experienced the highest critical stress. Hence, adequate percentage composition of E-glass and polyester reduces failure in hybrid glass composites in polymeric industries.
