A sabot segment molding apparatus and a method for molding a sabot segment therein, are provided in which wedge-shaped sections of carbon-fiber plies, impregnated with B-stage epoxy or thermoplastic resin, are stacked in a heated arcuate channel. Pressure is applied to the radial surface of the stack by a compression mechanism acting on a novel hinged wing assembly. The hinge pin is secured coaxially in the channel by a support mechanism, so that no vertical downward force is applied to the stack. Instead, a pair of hinged planar wing members rotate around the hinge pin toward each other, and compress the stack of wedge-shaped sections to the desired arcuate shape. The compressed stack is kept under a desired pressure and temperature for a desired period of time until a suitable 120 DEG sabot segment is formed.
