Abstract:
1. A ball bat extending along a longitudinal axis, the bat comprising: a barrel portion defining a primary tubular region, the primary tubular region being formed of a fiber composite material having wall thickness of at least 0.100 inch, the fiber composite material including at least first and second plies, the first ply including a first plurality of fibers aligned adjacent to one another and a first resin, and the second ply including a second plurality of fibers aligned adjacent to one another and a second resin, substantially all of the first and second pluralities of fibers of the first and second plies being generally aligned to define first and second angles with respect to the longitudinal axis, respectively, the first and second angles each being within the range of 45 to 90 degrees, the first and second plies having opposite polarities and being positioned with the second ply applied directly over the first ply, the first and second pluralities of fibers being sectioned such that the fibers continuously extend about less than half of the full circumference of the primary tubular region, the sectioned first plurality of fibers of the first ply retaining their angular alignment with respect to the longitudinal axis and the sectioned second plurality of fibers of the second ply retaining their angular alignment with respect to the longitudinal axis.
