Document Type and Number:
Japanese Patent JP4169799
Kind Code:
B2
Abstract:
A unique golf ball and related methods of manufacturing are disclosed in which the golf ball comprises one or more mantle layers comprising one or more metals, ceramic, or composite materials. Composite materials include silicone carbide, glass, carbon, boron carbide, aramid materials, cotton, flax, jute, hemp, silk, and combinations thereof. The golf ball may also comprise an optional polymeric spherical substrate inwardly disposed relative to the one or more mantle layers. The golf balls according to the present invention exhibit improved spin, feel, and acoustic properties. Furthermore, the one or more interior mantle layers prevent, or at least significantly minimize, coefficient of restitution loss from the golf ball, while also significantly increasing the moment of inertia of the golf ball.
