▎ 摘　　要

NOVELTY - The golf ball (20) has a first layer provided with a polybutadiene material with an embedded integrated circuit (IC). The IC transmits signal at a radiofrequency of 2.4 gigaHertz. A second layer is provided with polybutyrene material and a graphene material. The second layer is connected with a flexural modulus. A third layer is connected with second and fourth layers. The third layer is provided with an ionomer material. A cover layer is connected with the fourth layer, where thickness of the cover layer is 0.025 inch to 0.040 inch. Cores (25, 40) Cover (26) USE - Golf ball for use in a high speed testing device and a golf club. ADVANTAGE - The ball improves durability of golf ball core by incorporation of graphene in the core to improve the impact strength of the ball and durability of the core by using graphene and reduces higher mean time to fail upon repeated impact in a high speed testing device or a golf club in normal play. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a golf ball. Golf ball (20) Cores (25, 40) Cover (26)
