Abstract
A layered composite bat is designed to include fiber angles of orientation that are layered and progressive. The bat includes a multi-layered composite material configuration wherein progressing from an innermost layer to an outermost layer, the unidirectional fiber angle of orientation within each layer increases from an angle substantially parallel to the longitudinal axis of the bat to an angle substantially perpendicular to the longitudinal axis of the bat. In progressing from an innermost layer to an outermost layer, there also exists at least one instance where subsequent positive angles of orientation are separated by or vary by about 15 degrees. The bat may include multiple walls. Each wall contains layers that progress from a low angle to a high angle in 15-degree increments.
