摘要： A mandrel 10 suitable for forming a hollow part from a heat curable material includes an (a) an elongate central member 12 having a coefficient of expansion which is different than the coefficient of expansion of the cured heat curable material, (b) at least one lateral member 14, disposed at a first location 28 and projecting away from the outer surface 24 of the central member 12, the lateral member 14, being slidably attached to the central member 12, and (c) a rigid elongate strut member 16 having a coefficient of expansion substantially similar to the coefficient of expansion of the cured heat curable material. The first end 34 of the strut member 16 is affixed to the lateral member 14, and the second end 36 of the strut member 16 is affixed spaced apart from the lateral member 14.
