ABSTRACT:
A ball bat typically used in playing the game of baseball or softball is constructed of an inner layer bounded by first and second outer layers. The inner layer typically contains four inner lamina bonded together, while the first and second outer layers typically contain a single outer lamina. The inner laminas from the medial portion of the barrel of the bat, as well as the handle portion. The outer laminas form lateral portions of the barrel of the bat, and are gently tapered toward the handle of the bat. The thickness and relative position of each lamina is related to the results of non-destructive testing of the wood forming that lamina.
