One-directional tape and composite with hard structure on the basis of super-high-molecular polyethylene and the method of their manufacture

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.
