Abstract
The present invention relates to a tubular body such as a fishing rod or a golf club shaft. According to the present invention, a tubular body is made of reinforcing fibers impregnated with synthetic resin, having a reinforcing layer made of thermoplastic amorphous polymer fibers thereon. Therefore, the thermoplastic amorphous polymer fibers absorb the impact and keep the body proper free from being destroyed or damaged when the tubular body is shocked. In the case of a fishing rod, said fibers absorb and lessen noise so that only a bite of a fish can easily be noticed. In the case of a golf club shaft, the fibers lessen the impact vibration when the sweet spot of the club hits the ball so that it is possible to know whether the club head has hit the ball without fail.
