Numerical simulation on addition of Kevlar as reinforcement in CFRP (Carbon fiber reinforced plastic) laminates under low velocity impact

Abstract

Fibre Reinforced Polymer (FRP) laminates are used extensively in automotive and aerospace components because to their reduced weight, increased design freedom, increased durability, and reduced susceptibility to corrosion. The research of impact damage is crucial for composite materials utilised in these components. Impact circumstances and laminate designs play the biggest roles in determining how laminates react to impacts. The hybrid composite laminates in this work (made of CFRP and Kevlar) are subjected to an explicit numerical analysis of the low velocity impact damage behaviour for three distinct thicknesses. Modelling is done using ABAQUS/CAE on the composite laminate and impactor. Modelling is done using ABAQUS/CAE on the composite laminate and impactor. The laminates' characteristics were coded in a VUMAT subroutine, and the analysis was done using ABAQUS/Explicit. Numerical analysis results for the absorbed energy are compared to laminates reinforced simply with carbon. In comparison to bare CFRP laminates, the simulation results indicated that hybrid laminates had a better energy absorption capability.
