Abstract
Official abstract text for this publication.
Provided is a concrete reinforcing composite material that is impregnated with a thermoplastic resin having excellent alkali resistance and handleability. In a concrete reinforcing composite material 10, a core material 12 is formed from a fiber bundle of reinforcing fibers. The core material 12 is covered with a coating layer 14 made of a thermoplastic resin. The core material 12 is impregnated with the thermoplastic resin. The thickness of the coating layer 14 is 84 μm or more. The fiber volume content Vf of the core material 12 is 60% or more.
First claim
Opening claim text (preview).
1 . A concrete reinforcing composite material, comprising: a core formed by a fiber bundle of reinforced fiber; and a coating layer of thermoplastic resin, the coating layer coating the core, wherein the core is impregnated with the thermoplastic resin, a thickness of the coating layer is not less than 84 μm, and a fiber volume content V f of the core is not less than 60%. 2 . The concrete reinforcing composite material according to claim 1 , wherein a non-circularity of the concrete reinforcing composite material is 1% to 5%, and a non-circularity of the core is 1% to 6%. 3 . The concrete reinforcing composite material according to claim 1 , wherein a twist angle of the reinforced fiber is 0.087° to 15°. 4 . The concrete reinforcing composite material according to claim 1 , wherein a twist angle of the reinforced fiber is proportional to a distance from center of the core. 5 . The concrete reinforcing composite material according to claim 1 , wherein the thermoplastic resin is polyolefin resin. 6 . The concrete reinforcing composite material according to claim 1 , wherein the reinforced fiber is at least one type selected from the group consisting of glass fiber, basalt fiber, carbon fiber, and aramid fiber. 7 . A concrete reinforcing rebar containing the concrete reinforcing composite material according to claim 1 .
