Abstract
A composite ball bat includes multiple failure planes within a barrel wall. By including multiple failure planes in a barrel wall, the bat exhibits a drop in performance when subjected to rolling or other extreme deflection, with no temporary increase in barrel performance. Because the barrel performance does not increase, the ball bat is able to comply with performance limitations imposed by regulatory associations.
Claims7
A ball bat, comprising:
- a barrel comprising a composite laminate, wherein the barrel includes an external surface and an internal surface, such that a neutral axis defining a primary failure plane is located between the external and internal surfaces;
- a discontinuity within the composite laminate comprising a void bordered by at least one protrusion, the discontinuity creating an additional failure zone;
- and
- a handle attached to or integral with the barrel.
