Abstract
PURPOSE: To mold a reinforced resin tube having improved dimensional accuracy of diameter, by forming a resin-impregnated molding material layer, around an auxiliary mold mounted on a mandrel to semicure the resin, and by removing the mandrel to cure the material layer.
CONSTITUTION: The mandrel 1 having the ends 12 with a larger diameter than the central part 11, the inner cut 111 and outer cut 112, and the flanges 13 on both sides of the ends 12 outside, is mounted on the support shaft 2 by the clamp screws 3. The auxiliary mold 4 having the inner surface shape corresponding with the outer surface of the mandrel 1, the ends 42 with an outside diameter larger than the central part 41, and the flanges 43 on both sides of the ends 42 outside, is mounted on the mandrel 1. The resin-impregnated molding material is wrapped around the mold 4 to form and semicure the molding material layer 5 until the surface hardness becomes ≥ 20 in Barcol hardness. The clamp screws 3 are loosened to remove the shaft 2, and mandrel 1, and the material layer 5 is cured until the surface hardness becomes ≥ 40 in Barcol hardness, thus removing the auxiliary mold 4.
