Abstract
The invention provides a method of making a formable hockey stick blade, the method comprising: (a) providing a core having a blade element with a thickness, the core being made of expandable foam having a Poisson ratio of at least 0.33; (b) forming a preformed stick blade by wrapping the core with a layer of fibers pre-impregnated with a thermoplastic material; (c) placing the preformed stick blade in a mold; (d) applying heat and pressure to the mold for bringing the thermoplastic material to its amorphous form and for compressing the preformed stick blade such that the thickness of the blade element of the core is reduced; (e) cooling the mold such that the thermoplastic material is set; and (f) removing the formable stick blade from the mold.
