A front-facing armor system utilizing a composite laminate
backed by a high hardness substrate. The composite laminate
comprises a series of first and second layers. The first
layer of the bi-layer laminate system is a polymer with a
density of at least 1.8 g/ᵌ and having both an amorphous
and crystalline phase, and having phase transformation
pressure of at least 0.5 GPa at a temperature of 20° C. The
second layer of each bi-layer provides acoustic impedance
mismatch to generate reflections of the incident compression
wave following ballistic impact. Under ballistic impact, the
polymer comprising the armor system undergoes a shockinduced
transition resulting in a marked change in microstructure
and mechanical behavior, providing a significant
kinetic energy absorption mechanism.
