Evaluation of Static Impact Resistance in Nonwovens/Glass Plain Fabric Sandwich Structural Hybrid Laminates

Abstract:

This paper reveals the manufacturing process and static impact resistance of sandwich structural hybrid laminates composed of high-resilience bonding polyester /Kevlar intra-ply hybrid nonwovens and E-glass woven fabric. The effects of various weight ratio of Kevlar fiber on the mechanical behaviors, including tensile strength, tear strength, bursting strength and puncture strength, were evaluated. The experimental results indicated that the tensile strength and fracture work were both enhanced with the increase in Kevlar content. The tear strength on CD and MD exhibited opposite trends when varying the Kevlar content. The static bursting and puncture resistances were both enhanced with the promotion of Kevlar content. The failure mechanisms of the breakages were also analyzed.
