    • A prepreg winding method includes the steps of preparing a plate, a mandrel movable toward and away from the plate, and a press roll movable toward and away from the mandrel and having an axis parallel to the mandrel; mounting a prepreg on the plate, the prepreg being formed by impregnating reinforced fibers with a thermosetting resin sheet; winding a leading end of the prepreg mounted on the plate around the mandrel, and making a pressing force act on the plate and the mandrel therebetween with the prepreg sandwiched between the plate and the mandrel and making a pressing force act on the mandrel and the press roll therebetween with the prepreg sandwiched between the mandrel and the press roll; and winding the prepreg around the mandrel by rotating the mandrel and the press roll.

    • It is object of the present invention to provide a golf club shaft superior in accuracy, minimizing a displacement between thermosetting resin layers, capable of obtaining a feeling close to the feeling of a steel shaft, and superior in stability. To solve the above problems, a golf club shaft of the present invention uses a golf club shaft comprising a torsional rigidity holding layer made of thermosetting resin including reinforcing fibers diagonally crossed in the longitudinal direction of said shaft and a UD flexural rigidity holding layer made of thermosetting resin including reinforcing fibers aligned in parallel to the longitudinal direction of said shaft, characterized in that at least a part of said torsional rigidity holding layer includes a plain weave fabric layer obtained by winding and curing like a shaft-shape a plain weave prepreg which lets a plain weave fabric having mutually woven warps and wefts impregnate with thermosetting resin in such a way that said warps and wefts are diagonally crossed in the longitudinal direction of said shaft.
    • 本发明的目的是提供一种高精度的高尔夫球杆轴,使热固性树脂层之间的位移最小化,能够获得与钢轴的感觉接近的感觉,并且稳定性优异。 为了解决上述问题,本发明的高尔夫球杆轴使用高尔夫球杆轴,该高尔夫球杆杆杆包括由热固性树脂制成的扭转刚性保持层,该热固性树脂包括沿着所述轴的纵向方向对角交叉的增强纤维和由UD制成的UD抗弯刚度保持层, 包括与所述轴的纵向方向平行排列的增强纤维的热固性树脂,其特征在于,所述扭转刚性保持层的至少一部分包括通过卷绕和固化而获得的平纹编织织物层,如平面编织预浸料 使具有相互编织的经纱和纬线的平纹织物以热固性树脂浸渍的方式使得所述经纱和纬纱在所述轴的纵向方向上对角交叉。
