ONE-DIRECTIONAL TAPE AND COMPOSITE WITH HARD STRUCTURE ON THE BASIS OF SUPER-HIGH-MOLECULAR POLYETHYLENE AND THE METHOD OF THEIR MANUFACTURE Russian patent published in 2017 - IPC B32B37/24 F41H1/02 D06M17/00 C08J5/06 D06M10/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a unidirectional tape and a composite with a rigid structure based on ultra-high molecular weight polyethylene and a method for manufacturing them. The composite is made of a plurality of adjacent fiber-based layers, each fiber-based layer contains synthetic fibers with a high tensile modulus and is characterized by the presence of surfaces that are partially coated with a polymeric material. The fibers do not contain a protective coating, and the polymeric material is in direct interaction with the surfaces of the fibers. The production of bullet-proof fibrous composites is characterized by their improved bending properties, which correlates with the low depth of the composite impression. Composites are suitable for the production of solid bullet-proof products, including helmets.

EFFECT: creation of bullet-proof fibrous composites, which have improved properties for resistance to bullets and fragments.
