Graphene and carbon nanotube reinforced golf ball

Abstract:

A golf ball comprising an inner core comprising polybutadiene, and an outer core comprising a polybutadiene material, a graphene material and a carbon nanotube material (CNT) is disclosed herein. Improved durability of the core by using a mixture of graphene and CNT can result in higher mean time to fail (MTTF) upon repeated impact in a high speed testing device, or with a golf club in normal play.
