Abstract
A dual-core blade and method for manufacturing a dual-core blade are disclosed. The blade is formed with a first core portion and a second core portion comprising an epoxy having a plurality of expanded microspheres. The method of forming the two foams generally comprises sizing a foam core to form a first core portion and providing and preparing an epoxy mixture to form a second core portion. The first core portion and the second core portion of the epoxy mixture are placed into a preform, and the preform is heated slightly so as to cause the epoxy mixture to flow into the shape of the preform and around the first core portion. The first core portion and the second core portion are then bonded in a molding operation. The formed structure can form part of a hockey stick blade.
