FIELD: construction.
SUBSTANCE: composite reinforcement comprises bearing rod of low-module fibres and winding with ledges, besides bearing rod is arranged as reinforced with high-module fibres assembled into bundles evenly arranged in massif of low-module fibres. Ratio of linear densities of low-module fibres to high-module ones makes from 1.5 to 5.
EFFECT: high-module fibres have elasticity module, exceeding elasticity module of steel reinforcement, and are selected from carbon fibres, boric fibres, Kevlar fibres, fibres of ultrahigh molecular polymers.
