摘要:
A golf club head including an outside lower portion intended to rest on the ground, constituting the sole, a substantially plane front portion constituting the impact surface, and a rear portion constituting the body, wherein the club head includes an internal cavity limited at least partially by the walls of a steel shell in the lower and rear portion, and that at least the impact surface is a fiber-based composite material of which the modulus of the elasticity is greater than or equal 230 GPa.
摘要:
Golf club head comprising a shell extended laterally by a neck, said shell being constituted by a series of metal plates forming an interior cavity, whose front plate incorporates a support surface to which a hitting plate made of a plastic or composite material is attached. The support face of the front plate is a convex surface extending forward, and the hitting plate associated with it is such that its rear plate, which is supported on the support face, has a matching shape, while the hitting surface is a convex surface extending forward.
摘要:
The invention concerns a golf ball constituted of a three part structure, constituted of an elastomer core, an intermediate layer, and a thermoplastic envelope. The intermediate layer is made of a thermoplastic material containing at least 10%, and preferably at least 35% of ether block copolymer. The material may also be advantageously constituted of ether block copolymer to which is added 0 to 90% of ionomer(s) with respect to the total weight of the compound.
摘要:
Golf club head of the "iron" type, comprising a head body constituted by a shell (3) formed by a series of metal walls (9,10, 11) forming an inner cavity (4). The front wall (9) belonging to the series of metal walls is (AR) in relation to the hitting plane (P) in order to house a hitting wall (7) made of plastic or composite material.
摘要:
Process for manufacture of a golf club head incorporating a mounted hitting surface, comprising the steps of producing the body of the head from a series of metal plates, i.e., an upper plate, a lower plate, a peripheral plate, and a front plate comprising the front support face; bonding on its support face a hitting plate made of a plastic or composite material; and imparting to the hitting surface of the plate its final curved shape, which is convex toward the front.
