Personal armor resistant to sharp or pointed weaponry
According to exemplary inventive practice, a personal armor system includes a textile-based layer not exceeding ½-half-inch thickness, and an elastomeric coating not exceeding ⅛-inch thickness. The textile-based layer includes a fiber reinforcement and a resin binder. The combined areal density of the textile-based layer and the elastomeric coating does not exceed 2.5 psf. According to a first mode of inventive practice, the elastomeric coating is essentially a strain-rate-sensitivity-hardening elastomer, and the areal density of the textile-based layer does not exceed 2.3 psf. According to a second mode of inventive practice, the elastomeric coating is essentially a microparticle-filled strain-rate-sensitivity-hardening elastomeric matrix material, and the areal density of the textile-based layer does not exceed 1.7 psf. The microparticles (e.g., spherical glass microparticles) do not exceed, by weight, 30 percent of the strain-rate-sensitivity-hardening elastomeric matrix material. The textile-based layer affords ballistic protection; the elastomeric coating affords protection against sharp/pointed objects.
Variable areal density cross-plied fiber-reinforced composite ballistic material
This technology relates materials that are stab, spike and ballistic resistant and to stab, spike and ballistic resistant composite articles incorporating uniaxially oriented, non-woven fabrics. A fabric layer having a non-uniform areal density is formed having thick areas and thin areas, the thick areas having a greater filament/tape concentration compared to the thin areas. In said thick areas, agglomerated tapes/filaments will protrude from the fabric layer surface. Additional layers are then adjoined with the non-uniform layer to form a panel that has stab, spike and ballistic resistance, with protrusions at least partially spacing the additional layers from full, direct contact with the surface of the non-uniform fabric layer to thereby enhance flexibility and stab, spike and ballistic resistance of the whole.
Composite film
The invention relates to a composite film (1), preferably intended for use in the construction industry and/or preferably for use as a construction film, having at least one functional layer (2), at least one outer protective layer (3) and at least one inner protective layer (4), the functional layer (2) being arranged between the outer protective layer (3) and the inner protective layer (4). According to the invention, it is provided that the functional layer (2) is formed as at least a single-layer membrane layer, that the outer protective layer (3) and the inner protective layer (4) are formed as a nonwoven layer comprising a polyolefin, and that the outer protective layer (3) and/or the inner protective layer (4) comprises at least one bicomponent fiber (5) having a first component (6) and a second component (7), the first component (6) comprising a first polymer and the second component (7) comprising a second polymer as constituent.
TEXTILE ARTICLE FOR RADIO FREQUENCY (RF) ABSORPTION AND ATTENUATION
The present disclosure describes a textile article for radio frequency (RF) absorption and attenuation. The textile includes a laminate that is formed via curing a wet laminate at room temperature for a cure time, the wet laminate comprising a resin substrate and a reinforced fiber matrix. The reinforced fiber matrix may include one of a bamboo fiber matrix, a cotton fiber matrix, a polyester fiber matrix, a nylon fiber matrix, or a wool fiber matrix. The resin substrate may include a first portion of iron oxide particles and a second portion of the elastic polymer solution, the first portion of iron oxide particles being based at least in part on an RF signal range that the textile article is configured to absorb and attenuate. For example, the iron oxide particles may include Fe.sub.3O.sub.4Fe, Fe.sub.3O.sub.4Ni, or Fe.sub.3O.sub.4, and/or so forth.
INSTALLATION AND METHOD FOR PRODUCING A SINGLE- OR MULTI-LAYER NONWOVEN
