Title:
IMPACT RESISTANT PROTECTIVE MATERIALS FOR INCREASED SAFETY IN HOSTILE ENVIRONMENTS
Document Type and Number:
WIPO Patent Application WO/2022/203894
Kind Code:
A3
Abstract:
Disclosed is an improved anti-ballistic impact resistant protective material including a combination of at least a fronting material and a hard backing material wherein the fronting material is measured to be at least 25% softer in the Brinell scale than the hard backing material and methods of fabrication techniques, thicknesses, densities, areal density, localized placement of constituent materials, and temporal processing, thereby yielding a superior protective combination increasing the impact threat resistive performance at an aggregate areal density lower than the mass increase that would have been required by simply increasing the thickness of the harder backing material alone to achieve increased threat resistive performance. Further, a hardened iron based alloy in excess of 535 Brinell that performs with a bulge, crack, petal failure mechanism is disclosed.
