An experimental investigation on impact dynamics response of woven roved glass fiber reinforced polyester laminated composites

This research deals with the effect of stacking sequence over, the mechanical behavior of laminates that includes tensile, flexural, fractography, area of impact damage, and residual tensile strength. The angle-ply laminate specimens were analyzed theoretically and correlated with experimental results. The highest interlaminar shear strength 32.89 MPa was exhibited by (60/30/60/30)(S) with better transverse stiffness of 444 N/mm. Among the developed laminates, (60/30/60/30)(S) showed the highest rate of residual strength degradation of 0.271. It has been found that an increase in interlaminar shear strength decreases the impact damage resistance of the composites. The angle-ply laminate composites exhibited superior residual tensile and impact resistant properties when compared with uniply laminate composites.
