The performance of baseball and softball bats constructed from composite materials can be significantly affected by low temperatures. This is due to the inherent properties of the resin matrix used in these bats, which can become stiffer and less resilient in cold conditions. For instance, a bat that performs optimally at 70F might exhibit reduced trampoline effect and a lower batted ball exit speed at 40F.
Understanding the impact of temperature on composite bat performance is crucial for players and coaches. Using a bat that is too cold can not only decrease performance but also increase the risk of bat damage, such as cracking or delamination. Historically, this issue has led to the development of various techniques and technologies aimed at mitigating the negative effects of cold weather, including warming methods and specialized bat constructions. This awareness has evolved alongside the increasing popularity of composite bats, driven by their potential for greater performance compared to traditional aluminum bats.
