Abstract
Composite reinforcements (100, 100A, 100B, 100C) are formed by combining a first plurality of continuous fibers (102) with a second plurality of continuous fibers (106) with the first and second pluralities of continuous fibers (102, 106) being impregnated with at least one appropriate resin material (R1, R2, R3) and pultruded to form the reinforcements. The first and second pluralities of continuous fibers (102, 106) can be intermixed with one another or combined as a central core (104, 132) of the first fibers with a jacket (108, 108A, 108B, 134) formed by the second fibers. In either event, the combined fibers are formed as an elongated rod (110) and rigidified using the resin material. The first fibers are glass, either E-glass or S-2 glass, with the second fibers being either carbon, aramid, S-2 glass or AR-glass. The composite reinforcements of the present application, formed by combining these materials, have characteristics very similar to steel under tensile loading but with superior corrosion resistance and less detrimental deterioration characteristics.
