The fibers, polymer resins and application methods for the systems can vary substantially. The reinforcing fibers are made of either carbon, E-glass or aramid, and the polymers are either epoxy, polyester or vinyl ester. With some systems, the fiber is supplied pre-impregnated with polymer resin; with others, all the resin is applied during installation. In addition, the fibers can be supplied in rolls, pultruded strips or thin shells for wrapping columns.
