    • 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.
    • 复合增强件(100,100A,100B,100C)通过将第一多个连续纤维(102)与第二多个连续纤维(106)组合而形成,第一和第二多个连续纤维(102,106)被浸渍 与至少一种适当的树脂材料(R1,R2,R3)和拉挤成型增强材料。 第一和第二多个连续纤维(102,106)可以彼此混合或组合成第一纤维的中心纤芯(104,132),并具有由第二纤维形成的护套(108,108A,108B,134) 纤维。 在任一情况下,组合纤维形成为细长杆(110)并且使用树脂材料进行硬化。 第一种纤维是玻璃,即E玻璃或S-2玻璃,第二种纤维是碳,芳族聚酰胺,S-2玻璃或AR玻璃。 通过组合这些材料形成的本申请的复合增强材料在拉伸载荷下具有与钢非常相似的特性,但具有优异的耐腐蚀性和较差的劣化特性。
