Abstract: An improved method of reinforcing concrete is provided. A plurality of carbon fiber tubules may be added to the cementitious slurry so as to increase the cured concrete's tensile strength and resistance to corrosion.

Abstract: A carbon fiber tubule rod reinforced concrete. Carbon fiber tubule rods may have an outer surface, an interior wall, an interior housing, a first end and a second end. An opening may be exposed on the first end and the second end of the carbon fiber tubule rod. At least one side hole may be exposed along the outer surface. The carbon fiber tubule rod may be made from braided carbon fiber tow, printed on a 3D carbon fiber printer, or the like. The carbon fiber tubule rod may have a corrugated shape. A resin coating may cover the carbon fiber tubule rod. A plurality of carbon fiber tubule rods may be mixed with concrete, so that while mixing in a high speed, shear-type mixer, it may enter the carbon fiber tubule rods and surround the carbon fiber tubule rods inside and out.
