Abstract
A composite strand of thermosetting synthetic plastic resin reinforced with fibers of conductive or semi-conductive material is produced by a pultrusion machine and process which forms and impregnates the composite strand and pulls it through the stage of impregnation, followed by curing, and forming. At the impregnation stage liquid thermosetting resin is mixed with hardener and the fiber strand saturated with the mixture and rough formed. During the initial curing stage a cure is started by heating the fibers by use of inductive electrical wave energy and the heated fibers in turn heat the resin. Before final curing, the saturated strand is pulled through the finish die where it may be externally heated and wherein the saturated strand is given its final cross-sectional shape and external finish, and cured to completion immediately prior to final emergence at the exit end of the finish die.
