A process for molding a thermoplastic fiber reinforced article including the step of positioning a first thermoplastic tubular member on a first mandrel and a second thermoplastic tubular member on a second mandrel. Each tubular member is reinforced with oriented filaments. The first and second mandrels having the respective first and second tubular members thereon are positioned in a mold cavity and the remainder of the cavity is filled with a fiber reinforced thermoplastic matrix. The fiber reinforced matrix may be compression molded or injection molded.
