[Means for Solving the Problems]
The method for producing a tubular molded body of the present invention employs the following means in order to solve the above problems.
すなわち、本発明の要旨は、一方向引き揃え強化繊維束に樹脂を含浸させたプリプレグであって、繊維引き揃え方向に対して直角方向の凹凸係数Ｒｚが１５μ／ｍ以下であり、かつ、強化繊維目付が１２５ｇ／ｍ２以下であるプリプレグ（ア）と、一方向引き揃え強化繊維束に樹脂を含浸させたプリプレグであって、強化繊維目付が１５０〜２５０ｇ／ｍ２であるプリプレグ（イ）と、を繊維軸方向が直行するように貼り合せて積層プリプレグを得、プリプレグ（イ）を内側とし、かつ最終的に製造される管状成形体の周方向を補強するように前記積層プリプレグをマンドレルに巻きつけ、次いで樹脂を硬化して管状成形体とした後、マンドレルを抜き取る、管状成形体の製造方法にある。 That is, the gist of the present invention is a prepreg obtained by impregnating a resin into a unidirectionally aligned reinforcing fiber bundle, wherein the unevenness coefficient Rz in a direction perpendicular to the fiber aligning direction is 15 μ / m or less, and A prepreg having a fiber weight of 125 g / m 2 or less and a prepreg obtained by impregnating a unidirectionally aligned reinforcing fiber bundle with a resin and having a reinforcing fiber weight of 150 to 250 g / m 2. And a laminated prepreg obtained by laminating the laminated prepreg so that the fiber axis direction is orthogonal to the prepreg (a) and reinforcing the circumferential direction of the finally formed tubular molded body with the mandrel. And then curing the resin to form a tubular molded body, and then withdrawing a mandrel.
