ABSTRACT:
A lightweight rod is strengthened by one or more longitudinally extending reinforcing beads of fiber-resin material which are integrally formed with a rod composite jacket during a pultrusion manufacturing process. Specifically, lightweight cores or alternating lightweight and reinforcing cores are introduced into a larger diameter pultrusion die tube. These cores can be provided with a particular shape and/or they can be introduced to the die tube so that the distance between the outer surface of the core and the inner surface of the die tube is non-uniform. Resin coated fibers are channeled into the space between the cores and the die tube where these fibers are compressed and heated to form a cured product. The result is a lightweight rod having longitudinally extending reinforcing beads of fiber-resin composite material where the distance between the lightweight core and the die tube was significantly greater than the average core to die tube distance.
