  • Publication number: 20240075349
    Abstract: In a golf ball having a core, an intermediate layer and a cover, the ball and the sphere obtained by encasing the core with the intermediate layer have respective surface hardnesses such that (surface hardness of ball)<(surface hardness of intermediate layer-encased sphere); the ball has an initial velocity of ?75.0 m/s; and the core has a hardness profile in which the center hardness, the hardness at a midpoint between the core center and core surface, and the hardnesses at specific positions inward from the midpoint and at specific positions outward from the midpoint are optimized. Given the possibility that the rules limiting the distance traveled by a golf ball on shots by long hitters will change, this ball reduces the drop-off in distance on driver shots and iron shots taken by average hitters while increasing the drop-off in distance on driver shots taken by long hitters.

    Abstract: In a golf ball having a core and a cover with a plurality of dimples on the surface, the cover is formed primarily of polyurethane, the dimples have a specific volume occupancy ratio and the ball has a diameter of at least 42.8 mm. In an impact test carried out by hitting the ball with a driver at a head speed of 40 m/s, the sum t1+t2 of the time t1 required from initial contact by the driver with the ball for deformation of the ball to reach a maximum and the time t2 required from the state of maximum ball deformation for the ball and driver to separate is 660 ?sec or less. This golf ball makes it possible for golfers who have a high head speed and ordinary golfers who do not to compete without relying excessively on superiority in terms of distance.
