    摘要: A mold and a method for molding high strength, non-metallic fiber reinforced composite parts having a variety of (e.g., cylindrical) shapes that are lighter in weight than similar parts manufactured from metal. An unmolded non-metallic pre-form having long continuous fibers is placed around a mandrel, and a segmented, adjustable diameter compression ring is disposed in surrounding engagement with the pre-form at an upper position within an inwardly tapered compression ring support. The compression ring is formed from a plurality of loose compression ring segments that are initially spaced circumferentially from one another at the upper position of the compression ring support. The mandrel and the pre-form are first heated and then located in a press. The press is closed to push the compression ring and the heated mandrel from the upper position of the compression ring support, at which the compression ring has an open configuration and a wide diameter, to a lower position, at which the compression ring has a closed configuration and a narrow diameter. As the compression ring is pushed to the lower position, the compression ring segments slide along the inwardly tapered compression ring support so as to be moved end-to-end one another to apply a compressive force for consolidating and shaping the heated pre-form into the molded part.
