Polymer matrix composites (PMCs) offer several advantages compared to traditional metallic counterparts when employed in high-performance products that need to be lightweight, yet strong enough to sustain harsh loading conditions - such as aerospace components and protective structures in military applications- armours, helmets, and fabrications retrofitted to transport vehicles and bunkers. These are often subjected to highly dynamic loading conditions under blast and ballistic impacts. Severe impact energy involved in these dynamic loading events can initiate discrete damage modes in PMCs such as matrix cracking, matrix splitting, delamination, fibre-matrix debonding, fibre micro-buckling and fibre pull-out. Interaction of these damage modes can severely reduce the load carrying capacity of such structures. This needs to be understood to design structures with improved resistance to such loading.
