Finite Element Analysis of IPN Reinforced Woven Fabric Composite

Abstract

A series of E-Glass fiber reinforced polyurethane (PU)/vinyl ester(VER) resin interpenetrating polymer network (IPN) composites were prepared. The Mechanical Properties like tensile, flexural and impact of IPN composite were studied. Results revealed that addition of PU increases the impact strength by 8.33%, 7.69%, 14.28%, 12.5%, 11.11% for the proportinate of 0%PU, 10%PU, 20%PU, 30%PU, 40%PU, 50%PU respectively, at the slight expense of decrease in flexural and tensile modulus. The obtained experimental results were compared with the Finite Element Analysis data's (ANSYS 10). The comparison shows good agreement with experimental data's.
