Abstract:
1. A method for manufacturing a fiber-reinforced composite sabot by laminating a prepreg fiber in the radial direction comprising: a sub-segment forming step wherein four or more of sub-segments are formed with predetermined form by superposing a pluraity of plies; a segment forming step wherein three or more of segments are formed by laminating the sub-segments; a piece forming step wherein three pieces are formed by laminating the three or more of segments, each of the three pieces including an arc surface and two 120 degree surfaces; a sabot forming step wherein a sabot is formed by combining the three pieces; the piece forming step further comprising a reinforcing step wherein two or more plies are superposed and reinforcing bands are continuously laminated on two or more surfaces of the arc surface and surface and the two 120 degree surfaces; the reinforcing step further comprises a step wherein hoops formed with superposed two or more piles are continuously laminated on the arc surface of each piece; and a spare processing layer is laminated on the outermost layer of the arc surface of the piece.
