Abstract
The invention relates to a golf ball having a substantially spherical inner core, a layer of high tensile elastic modulus fibers wound about the inner core, and a molded layer of a polymeric material surrounding the wound layer. The high tensile elastic modulus fibers have a tensile elastic modulus of at least 10,000 kpsi. The invention also relates to a method of making a golf ball and includes providing an inner core, winding a high tensile elastic modulus fiber on the inner core to create a wound layer, and molding an outer layer of polymeric material about the wound layer. The inner core may be made of resilient materials or a center wound with a low modulus fiber and provided with an initial tension.
