Abstract
A composite ball bat includes a bat body made of a multilayer fiber composite material and including a hollow barrel, a handle and a tapered section joining the barrel to the handle and having an outer diameter reducing gradually from the barrel toward the handle, and a tube member coaxially mounted in the hollow barrel of the bat body and having a hardness higher than that of the hollow barrel of the bat body. In this way, the composite ball bat of the present invention can use the tube member to improve the hitting effect while reducing the weight.
