最近,日本精工株式会社发明了一种新型的钓鱼竿。此种鱼竿的管型竿体系用玻璃布或合股纱片成型而得,杆体的轴向方向使用实心纤维,环向方向使用中空纤维。 这种新型的钓鱼竿竿体与其他的鱼竿竿体相比,其纵横配置排列的增强纤维能够负载挠曲时所受的张力及压缩力,特别是轴向方向的环向纤维能够负载周边方向的张力及压缩力。 一般的薄壁钓鱼竿竿体,随着其弯曲挠度的增大,受到弯曲应力的圆形断面开始变形成扁平状,
Recently, Japan’s Seiko Co., Ltd. invented a new type of fishing rod. The tube rod system of such rods is made of glass cloth or plied sheer, with solid fibers in the axial direction of the rods and hollow fibers in the circumferential direction. Compared with other fishing pole bodies, the novel fishing rod pole body has the advantages that the reinforcing fibers arranged in the longitudinal and the lateral directions can bear the tension and the compressive force when flexed, and especially the axial fiber in the axial direction can load the periphery Direction of tension and compression force. The general thin-walled fishing rod pole body, with its bending deflection increases, the circular section under bending stress begins to deform into a flat shape,
