Composite Bats quickly became a popular alternative to aluminum alloy softball and baseball bats in the mid 2000’s. Currently, nearly every manufacturer of baseball bats and softball bats produces composite bats. Composite bats ushered in a new era where the sweet spot of a baseball bat could be finely tuned by adding or subtracting carbon fiber mesh in certain areas of the bat. Due to the strength of the composite material in the bats, bat makers could make the walls thinner while still maintaining structural integrity. This advance in baseball and softball bat making allowed for huge sweet spots and nearly made vibration a thing of the past.
