Abstract: A protective barrier having antimicrobial and antiviral properties. The protective barrier comprises a filtration media structure. The filtration media structure comprises inner melt blown nonwoven filtration media, an outer melt blown nonwoven filtration media, and a channeling layer. The channeling layer is sandwiched between the inner and outer filtration media layers. The channeling layer comprises a plurality of filaments. Each filament is constructed having a non-round cross-section. The filaments are arranged in a three-dimensional (3D) structure configured to disturb laminar flow through the protective barrier. The protective barrier may further comprise an inner layer and an outer layer encapsulating the filtration media structure.

Abstract: A ballistic laminate structure in sheet form includes first and second pre-annealed nonwoven fabric layers. Each fabric layer is constructed of a loosely assembled array of unidirectionally-oriented, untwisted, high performance fibers. The layers are joined together at an angle to form a dimensionally stable cross-plied fabric.

Abstract: The present invention provides a process for producing a prepreg of high modulus reinforcing fibers, the process comprising the steps of: a) providing a reinforcing fiber bundle layer wherein such bundle contains a thermoplastic and/or crosslinking resin within the fiber bundle; b) providing a layer of a thermoplastic and/or crosslinking material layer on at least one side of the high modulus fiber layer of step a); c) compressing the layers from step b) under an appropriate amount of heat and pressure, and thereby producing a prepreg of high modulus reinforcing fibers.
