It is an object of the present invention to provided a fiber reinforced plastics (hereafter referred to as " FRP ") bar. The aim of the present invention is to improve the known FRP bar. The said bar comprises a FRP core and a base resin in which the FRP bar is impregnated, and the peripheral surface of the core is coated axially with a cladding of bulked glass yarn reinforced plastics. Since the peripheral surface of core is coated axially with the cladding of bulked glass yarn reinforced plastics, the fiber reinforced plastics bar obtained in this invention has an effective roughness in the external surface of the core of the fiber reinforced plastics bar, which can improve the bond stress to concrete and therefore increase the lifetime of the reinforced concrete structures. The fiber reinforced plastics bar can be used to reinforce the concrete instead of steel rebar, and can be used widely in the buildings under the worse environment, such as marine structures, parking area and bridges where the antifreeze is used, and the like.
