Abstract:
A first reinforcing fiber layer is formed of reinforcing fibers which are wound around an outer periphery of a mandrel. The reinforcing fibers are aligned in parallel to a direction (+θ direction) in which the reinforcing fibers intersect with an annular direction (0° direction) of the mandrel, and seamlessly continue in the annular direction of the mandrel by an amount of at least one rotation.
