Abstract

A fully threaded composite reinforcing rod (85) formed by providing a reinforcing material supply of fiber strands rovings (16); a resin supply bath (30), and a puller (80) for pulling the resin-impregnated reinforcing material through the resin bath. A hot compression (or autoclave) apparatus includes two half autoclave molds (50), which can be arranged in a reciprocating die autoclave (60) or a tractor die autoclave (70) process. A mandrel or plastics tubing core is used to form a hollow shape of the composite materials to get an external threaded composite tubing. The two autoclave molds (51, 53) have an internal thread and clamp to form the threaded section in the outer of the resin-impregnated reinforcing material (43). The molds press and squeeze the resin out of the impregnated fibers to the mold internal surfaces, and push the outer fibers which may be the basic longitudinal roving fibers or may include a wrapped mat and/or helically wrapped fibers toward the crest of the thread of the molds so that the thread when formed is reinforced by fibers extending into the core of the rod.
