The dynamic performance of novel multilayered hybrid composite laminate

Abstract

Due to an increase in the need for improvement of impact resistance of conventional composites, hybrid composites are evolved. This research article presents the dynamic characteristics of a novel two-component hybrid composite plate under transverse impact loading. The multilayered hybrid composite laminate is fabricated using woven fibreglass fabric as skin material and thermoplastic polycarbonate sheet as the core. High strength, medium viscous epoxy matrix is used for bonding the skin and core materials. The hand layup followed by a compression molding technique is used for producing the laminate. The test samples are impacted with a minimum energy of 45 J to a maximum energy of 60 J to obtain rebound, penetration and perforation phenomenon at room temperature. Load–energy–displacement–time curves are plotted to understand the transient behaviour of the composite plates. Results are compared with the pure counterparts available in the literature in terms of impact resistance. It is inferred that the novel multilayered laminate being in lightweight about 19.17% as compared to conventional laminate presented by Evci and Gulgec (J Compos Mater 48:3215–3236). Further, the novel composite has provided less damage area with 16.66% of enhanced impact resistance in terms of energy required for complete perforation. The investigation revealed the possibility of replacing conventional materials with hybrid laminates in structural, defense and automotive applications, where impact resistance and light weight has much importance.
