CST Composites (Caringbah, Australia) has introduced a line of pultruded structural laminates composed of unidirectional carbon fiber-reinforced polymer (CFRP) that can be used for reinforcement of concrete, metal, wood and composite structural members. They are available in a range of sizes from 50, 75, 100, 120 and 150 mm (2, 3, 4, 4.7 and 6 inches) wide varying in thickness from 1 to 4 mm (0.04 to 0.16 inch). The strips are available in three stiffnesses/strengths. Standard, intermediate and high modulus carbon fiber grades are combined via continuous pultrusion with a high-performance epoxy resin to make the laminate. The resulting product reportedly offers high ultimate tensile strength, high modulus of elasticity and good fatigue and corrosion resistance. Typical applications include reinforcing members for wind turbine blades, building/bridge reinforcement and marine structure stiffening. The profiles can be supplied with roughened peel ply finish to provide adhesion and minimal substrate preparation required prior to bonding.
