GOLF BALL HAVING HIGH INITIAL VELOCITY |
摘要 |
A multi-layer ball includes a core made of a high energy material such as a highly neutralized polymer and a cover made of a deadening material. A specified relationship exists between the compression and coefficient of restitution of the core and of the ball. The initial velocity of the ball is higher than what would be expected based on the coefficient of restitution of the ball compared to prior balls. The use of the deadening material allows the coefficient of restitution of the ball to be relatively low, which can yield improved spinnability in the half wedge shots while maintaining driver distance.
