Abstract
Composite hockey stick includes an expanded polyvinylchloride foam core in the shape of a handle attached to a blade, a first mesh composed of at least one of fiberglass and carbon fibers tightly surrounding at least a portion of the expanded polyvinylchloride foam core, and at least one additional mesh composed of at least one of fiberglass and carbon fibers tightly surrounding at least a portion of the first mesh. Preferably, each mesh in a direction outwardly from the core has a greater weaving angle with respect to the core than a preceding mesh, to thereby provide an offsetting of threads of one mesh to another.
