Abstract
A hockey stick comprises a shaft and a blade. The blade is configured to impact and exert energy on a hockey puck. The blade comprises a core that is generally enclosed within an outer layer. The core comprises a foam-filled cell structure having cell walls that define foam-filled cells. The cell walls of the core structure extend in a direction generally from the front face toward the rear face of the hockey stick blade.

A method for making a sporting implement blade portion configured to withstand repeated impacts, comprising:
- providing a core comprising a foam-filled cell structure, the cell structure comprising a plurality of spaced apart cell walls that cooperate to define a plurality of cells therebetween, the cell walls arranged so that each cell has a longitudinal axis, the foam being disposed in the cells;
- and
- enclosing the core in a generally rigid outer layer comprising at least one composite layer of fibers entrained in a cured resin, the outer layer having an impact surface;
- wherein the cell structure is arranged relative to the outer layer such that the longitudinal axis is generally transverse to the impact surface.
A sports stick having a handle portion and a contact portion, the contact portion configured to impact a sports implement and having a cover comprising a primary impact face and a secondary impact face that generally oppose one another, and a generally rigid elongate spine extends between the primary and secondary impact faces along the length of the contact portion, the contact portion further comprising an upper core and a lower core substantially surrounded by the cover, at least one of the cores comprising a celled structural member constructed of a different material than the cover and comprising a plurality of cell walls, the cell walls arranged to extend generally in a direction from the primary impact face to the secondary impact face, wherein the upper and lower cores are separated from one another by the elongate spine.
