Advanced cured resin composite parts and method of forming such parts

A unique composite material impregnated with a heat curable resin comprising a layer of conductive fibers and one or more resin carrying layers is utilized to reinforce utility poles by wrapping the material around a portion of the utility pole and causing a current to flow through the conductive fibers to resistively heat the material to the resin. The composite material can also be incorporated into molds to produce cured composite parts. The composite material is also used in the construction of large parts without the need for huge, expensive molds. The conductive fibers in composite parts are oriented in a manner to ensure that the entire part is thoroughly heated during the curing process.
