COMPOSITE REINFORCEMENT Russian patent published in 2017 - IPC E04C5/00 C08L63/00 B32B17/04 C08J5/24 B82Y30/00 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely non-metallic composite reinforcement, which is used for reinforcing thermally insulated wall structures, monolithic concrete and prefabricated structures, for use in structural elements of buildings in the form of individual bars for reinforcing the foundation bed of buildings and structures, including foundations for highways and roads, and for anchoring retaining walls and structures in the ground. The invention comprises a support rod of glass or basalt roving and high modulus fibers impregnated with a binder. The binder is a composition of epoxy-diane resin, polyethylene amine hardener, dibutyl phthalate plasticizer and carbon nanocomposite additive in the amount of up to 1% by volume of the binder resin. The additive contains multi-layer carbon nanotubes in the quantity of no less than 45-50% by weight of carbon nanocomposite additions; it is made of brown sphagnum in conditions of mechanic activation of its pyrolysis products for at least 8 hours of treatment.

EFFECT: invention allows to obtain reinforcement with high elastic modulus with reduced amounts of high-modulus fibers being used, which allows to meet the requirements of reinforced products in terms of their degree of deformation.
