纤维强化树脂中空体及其制造方法
一种纤维强化树脂中空体(10a)，其具有轴向取向纤维层(1)和非轴向取向纤维层2(3)，轴向取向纤维层(1)包括相对于该纤维强化树脂中空体的轴向平行地取向的强化用纤维；非轴向取向纤维层2(3)层叠在该轴向取向纤维层的内侧和外侧中的至少一侧，并且包括取向方向与该轴向取向纤维层不同的强化用纤维。所述非轴向取向纤维层包括一层以上的周向取向纤维层和一层以上的无取向纤维层，其中，周向取向纤维层包括相对于所述中空体的周向平行地取向的强化用纤维，无取向纤维层包括不沿特定方向取向的强化用纤维。
A fiber-reinforced resin hollow body includes an axial-direction fiber layer containing reinforcing fibers aligned parallel to an axial direction of the hollow body, and a non-axial-direction fiber layer provided on top of at least one of an internal and an external side of the axial-direction fiber layer, and containing reinforcing fibers oriented in a direction different from the alignment direction of the axial-direction fiber layer. The non-axial-direction fiber layer includes one or more peripheral-direction fiber layers containing reinforcing fibers aligned parallel to a peripheral direction of the hollow body, and one or more non-aligned fiber layers containing reinforcing fibers not aligned in a specific direction.
