I'm sure carbon has more damping than steel. Golf shafts are a different application, because they have resonances in the range of the typical excitation input. Hitting a golf ball is almost a perfect impulse, which excites a significant frequency band. And due to the length of the shaft, the transient vibrations last for a measurable length of time. I'll bet someone filled golf club shafts with a damping elastomer. Okay, I asked google https://www.google.com/search?q=goll...hrome&ie=UTF-8

Seems like most people put the damping in the head of the club
