METHOD OF MANUFACTURING THE FIBERGLASS ARMATURE Russian patent published in 2017 - IPC E04C5/07 

FIELD: construction.

SUBSTANCE: method of manufacturing fiberglass reinforcement provides for the formation of a fiber bundle of fiberglass, impregnation with a solution of a polymeric binder, shaping the rod preform with its profile until the polymerization of the binder is completed, the spiral winding of the rod preform is a twisted fiberglass yarn impregnated with a binder, curing the binder. Before winding the rod preform, at least one impregnated fiberglass yarn is longitudinally laid on it, and after winding this thread is notched, then the binder is cured. Not impregnated with a binder fiberglass yarn is cut at each step of the winding.

EFFECT: part of the cut filaments from fiberglass that project above the surface of the rod increases the strength of the adhesion of the fiberglass reinforcement to the concrete.
