METHOD OF MAKING HOCKEY STICKS ABSTRACT A plastic hockey-stick is made in three layers, around a core. The blade-core is retained but the handle-core may either be retained or withdrawn during manufacture. The inner layer is of hoop-laid strands, which gives rigidity to the cross-sectional shape of the handle, enabling the handle to be hollow. The middle layer is of length-laid strands, for good bending strength. The outer layer is of e.g., twisted strand woven cloth, for surface toughness. The enwrapped core is impregnated with resin, and compressed in a mould during curing. The resulting stick combines lightness, strength, resilience, non-dangerous failure mode, and enconomy of manufacture. Pat 6291
