Abstract Designing lightweight composite panels that can resist extreme impulsive loadings is of great interest for defence and infrastructure protective applications. In this work, a finite element model is developed to understand the deformation and failure mechanisms of a multilayered elastomer/fibre-reinforced polymer (FRP) composite panel under blast. Fibre (E-glass fibre) and matrix (vinylester resin) damage and degradation of individual unidirectional composite laminas are modelled using the Hashin failure model. The delamination between composite laminates is captured by three-dimensional bilinear cohesive elements. A thin elastomer (polyurea) layer is applied to the back face of the panel to reduce damage to the composite laminates. The predicted deformation histories, evolutions of fibre/matrix damage patterns, and inter-lamina delamination are captured and compared between monolithic and hybrid elastomer/composite panels. The model reveals the important role of the elastomer layer in improving panel performance by effectively mitigating the transmitted impulse to the back face of the panel and reducing delamination, while maintaining overall stiffness.
