Abstract
A barrel of a ball bat may include a composite laminate with a plurality of composite plies. One or more translaminar elements may pass through the composite plies and around a circumference of the barrel to reduce relative movement between the plies. The translaminar elements may include a first line of stitching, which may include aramid fiber. In some embodiments, the first line of stitching forms two or more coils around the barrel. Lines of stitching may be positioned on opposing sides of a center of percussion of the ball bat. In some embodiments, the translaminar elements may include a line of staples distributed around the circumference of the barrel. A method of making a ball bat may include arranging plies of composite material to form a cylinder, passing a first translaminar element through the plies, and curing the assembly of plies to form a barrel of the ball bat.
