ABSTRACT:
There is disclosed a golf ball including a layer made of a shape memory alloy. For example, fine thread of a shape memory alloy is wound around a core so as to provide a shape memory alloy layer between the core and a cover of the golf ball. In this structure, the shape memory alloy layer provides an effect of tightening the core, thus improving the golf ball's resiliency, resulting an increased travel distance. Moreover, since the shape memory alloy layer has a high specific gravity, the moment of inertia of the golf ball increases, so that the spin and roll performances of the golf ball are improved. Furthermore, the shape memory alloy layer having higher strength and hardness functions as a reinforcement layer of the cover, thereby improving cut resistance and impact durability of the cover.
