The invention relates to the technology of manufacturing reinforcing FRP composite elements for reinforcement of conventional and prestressed building structures. With the help of manufacturing FRP composite rebar of the periodic profile, it includes the stretching of the formed and impregnated with a polymer binder cloth from roving threads through a squeezing device, which is assembled into a beam through a die, a feed to the periodic profile formation unit, a polymerization chamber, cooling blocks and cutting the product. At the same time, after the formation of the roving beam of the bearing rod in the die, pre-twisted threads are used as a periodic profile, and their application occurs with preliminary tension. Thus, the quality of the produced rebar is greatly increased due to larger bonding strength. The strength of adhesion to concrete increases, due to the innovative process of a pre-tensioned roving periodic profile in the form of ribs along the length of the FRP composite rebar.
A method for manufacturing FRP composite rebar with a periodic profile, including pulling a formed and impregnated with a polymer binder cloth from roving threads through a squeezing device, forming a rod, periodic profile, polymerization, cooling and cutting of the product, characterized by the fact that after impregnation, on the radial surface of a rod formed from impregnated With a pre-tension roving binder, a periodic profile is formed from the roving threads that have undergone the process of pre-axial twisting, while the thread of the periodic profile is impregnated with a binder from the rod itself when applied.
