Abstract
The bat of the present invention has a barrel with a thinner outer shell in compressive and/or adhesive engagement with an insert laminate comprised of one or more pieces of a thin metallic (preferably titanium) sheet (or foil) and one or more sheets of a composite material. The titanium portion of the insert laminate may be on the inner-most portion of the insert, may be on the outer-most portion of the laminate, or may be in the interior of the laminate (that is, with one or more sheets of composite material on either side of it). Alternatively, the bat may simply be provided with only a titanium insert. In yet another set of embodiments, the titanium sheet may be replaced by another suitable metallic sheet. In all embodiments, the reinforcing sleeve allows the barrel portion to deflect farther when impacted by an object such as a ball without detrimental yielding (denting) and increases the rate of return of the barrel wall.
