Abstract:
A ballistic composite armor article includes a multi-layer hard armor sheet that has at least first and second unidirectional yarn monolayers. The second unidirectional yarn monolayer is transversely oriented with respect to the first unidirectional yarn monolayer, and there is at least one polymeric binder layer arranged adjacent to and stabilizing at least one of the first and second unidirectional yarn monolayers. The yarns of the first and second unidirectional yarn monolayers include respective fiber bundles that have a lateral spread factor ranging from negative lateral spread to a positive lateral spread of less than 306%.
Abstract:
A ballistic-resistant composite includes at least one layer that has a network of ballistic fibers and a resin matrix. The resin matrix includes maleic anhydride-grafted polypropylene (MA-g-PP).

Abstract:
A ballistic-resistant composite includes at least one layer that has a network of ballistic fibers and a resin matrix. The resin matrix includes blocked isocyanate that is composed of isocyanate bonded with a blocking agent. The resin matrix is cross-linkable by heating to a temperature that causes the isocyanate to liberate from the blocking agent and the liberated isocyanate to reactively cause cross-linking of the resin matrix.
