Abstract: This invention describes the use of a polycarbonate-siloxane block copolymer in the fabrication of various components, especially those subject to repeated impact, for devices such as baseball and softball bats. This material has been shown to possess excellent impact fatigue resistance, a benign mode of failure, and an ability to maintain its shape following impact that was not observed in any other tested polymers.
