    摘要: A bimetallic golf club head having a weight body for lowering the center of gravity of the golf club head in order to increase vertical gear effect upon impact with a golf ball, while also providing for an isolation layer between the golf club head's weight body and a main body portion comprising a ball striking front section. One purpose of the isolation layer is to isolate, or reduce the combination of, the impact vibration frequency pattern of the main body and the vibration frequency pattern of the weight body, thereby preserving the desirable feel and playability of a single metal golf club head while enjoying the improved performance of a low center of gravity golf club head. Another purpose of the isolation layer is to minimize or reduce the galvanic/intermetallic reaction between two different metallic materials that are placed in direct contact.

    摘要: The present invention is a golf club (30) having a club head main body (34) with a hollow interior (49), a support layer 41 defining a depth of a recess (38), a polymer insert (40) in the recess (38), an isolation layer (52) and a weight body (50). The polymer insert (40) is composed of a thermosetting polyurethane material having a Shore D hardness in the range of 42 to 55, and a Bayshore rebound in the range of 51 to 60. The preferred thermosetting polyurethane material is formed from a p-phenylene diisocyanate prepolymer and a curing agent. The golf club (30) is preferably a putter, however, it may be a wood or an iron. The particular thermosetting polyurethane provides a soft striking face for feel and a good rebound for distance. The weight body (50) is preferably composed of a tungsten alloy, and the isolation layer (52) is preferably composed of a thermoplastic polyurethane.
