A method of reprocessing a fiber composite part to form a preform is provided including determining a location having a longest stretch of continuous, unidirectional fibers in the part, determining an axis generally closest to and parallel to the fibers at the location, suspending the part from an anchor point within a heated cavity, heating the part to a temperature above a glass transition temperature and below a melting temperature of the resin of the part, and applying at least one force vector to the composite part, the sum of such vectors being parallel to the axis, wherein fibers of the part realign in a direction generally parallel to the sum of the force vectors, and wherein the composite part yields in the direction of the at least one applied force vector to provide a preform.
