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 insert ignore into journalissuearticles values(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.
