BALL BAT INCLUDING A FIBER COMPOSITE COMPONENT HAVING HIGH ANGLE DISCONTINUOUS FIBERS

摘要

A ball bat extending about a longitudinal axis. The bat includes a barrel portion defining a primary tubular ball impact region. The barrel portion is formed of a fiber composite material. The fiber composite material includes at least first and second plies. The first and second plies include first and second pluralities first and second resins, respectively. Substantially all of the first and second pluralities of fibers of the first and second plies are generally aligned to define first and second angles with respect to the axis, respectively. The angles are each within the range of 45 to 90 degrees. Each of the plies is sized to extend about the full circumference of the barrel portion. The first and second pluralities of fibers are sectioned such that the fibers do not continuously extend about the full circumference of the impact region.

1. A ball bat extending along a longitudinal axis, the bat comprising:
a barrel portion defining a primary tubular region, the barrel portion formed at least in part of a fiber composite material, 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, each of the first and second plies being sized to extend about the full circumference of the barrel portion, the first and second pluralities of fibers being sectioned such that the fibers do not continuously extend about the full circumference of the primary tubular region.
