Abstract
A baseball bat having a lightweight core comprised of an elongated handle portion and a striking portion, wherein the handle portion and/or the striking portion is/are over wrapped with a singular thin external polymer composite skin bonded with resin directly and rigidly to the core forming a structural sandwich resulting in reduced weight, improved strength, stiffness and durability, thereby providing increased bat speed and improved hitting distances.

A baseball bat having an outermost striking surface comprising:
- a lightweight core, said core comprising:
- a shaft having a longitudinal handle portion at one end of the bat for manipulation by a user during use of the bat, said handle portion made of a lightweight material other than foam, and a longitudinal striking portion at a second opposite end of the bat for striking by the user, said striking portion made of a lightweight foam;
- and
- a singular external polymer composite skin rigidly bonded with an adhesive resin directly to the exterior surface of said handle portion and said striking portion of said core, said polymer composite skin comprising fibers impregnated with said resin and forming the outermost striking surface of the bat,
- wherein a portion of said handle portion extends into and is encased by said striking portion,
- whereby the weight of the bat is lower than the weight of a conventional metal or wood bat and whereby the strength, durability and performance of the bat is improved.
