Carbon composite material leaf spring manufacturing process according to the invention,
A first step to open the upper mold plug in the first pin on the left side a first groove bottom surface of the lower mold, plugs into the second pin on the right side a second groove bottom surface; Winding the winding member so that one end of the winding member away from the inner surface of the winding member on the first pin, to release said winding member to the second pin, the inner surface of the other end of the winding member wherein the winding member and a second step for the winding take-up member to touch to the second pin; Only it writes stacking the winding member on the winding member, by repeating the second step, to form a first connection portion in exploded side on the left side of the stacked winding member, and forming a second connection in exploded side to the right , a third step of forming the first connection portion and the second body portion between the second connecting portion; A fourth step of the winding member when deposited to a thickness that is set, covering the upper mold to the lower mold, and subjected to heat curing the resin contained in the laminated winding member; Characterized in that it comprises a; and a fifth step of taking out the stacked winding member to open the upper mold.
