Abstract
A governed performance hard shell bat designed to ensure ball exit speed approximating and not exceeding that of a wood bat of comparable weight and geometry is comprised of a thin wall hard shell such as reinforced resin composite or of metal such as aluminum or titanium or alloys thereof filled with light weight semi-rigid material such as a syntactic foam in the hitting area, the bat having longitudinal flexibility approximating that of a similarly shaped wood bat. The filler material has a sectional density and hardness correlated with the thickness of the metal shell wall in the hitting area and may be cast in the thin wall hard shell or it may be pre-formed and subsequently inserted into the shell. The filler has a sectional density in the range of from 10-30 lbs./cu. ft.
