SHAFT MADE OF FIBER-REINFORCED COMPOSITE MATERIAL |
| 摘要 |
Provided is a shaft made of a fiber-reinforced composite material including: a straight layer having a reinforcement fiber oriented in an axial direction; a first reinforcing layer provided outside the straight layer and having a first carbon fiber; and a second reinforcing layer provided outside the first reinforcing layer and having a second carbon fiber, wherein a tensile elastic modulus of the first carbon fiber and a tensile elastic modulus of the second carbon fiber are different from each other and are smaller than that of the reinforcing fiber in the straight layer. |
