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. [Continues.]
