WAYER COMPOSITE FITTINGS AND METHOD OF ITS MANUFACTURE Russian patent published in 2017 - IPC E04C5/07 

FIELD: construction.

SUBSTANCE: composite reinforcing bar includes twisted strands, including fibers and fastened with a polymeric binder. Each bundle is formed of yarns, each of which is twisted from at least two monofilaments, and the direction of twisting of the tows is opposite to the direction of twisting of the monofilaments. The method of manufacturing a composite reinforcing bar is to form bundles comprising fibers, impregnating the tows with a thermosetting polymer composition, twisting the tows to form a rod, and curing the polymer at a high temperature. In this case, the formation of bundles is carried out from yarns obtained by twisting monofilaments, and twisting of bundles is carried out in a direction opposite to the direction of twisting of the monofilaments.

EFFECT: increasing the resistance of the reinforcing bar to bending stresses due to the uniform distribution of the polymer binder along the thickness of the rod.
