BI-MATERIAL GOLF CLUB HEAD HAVING AN ISOLATION LAYER

摘要

A bi-metallic golf club head (10) having a weight body (16) for lowering the center of gravity of the golf club head (10) in order to increase vertical gear effect upon impact with a golf ball, while also providing for an isolation layer (14) between the golf club head's weight body (16) and a main body portion (12) comprising a ball striking front section (30). One purpose of the isolation layer (14) is to isolate, or reduce the combination of, the impact vibration frequency pattern of the main body (12) and the vibration frequency pattern of the weight body (16), 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 (10). Another purpose of the isolation layer (14) is to minimize or reduce the galvanic/intermetallic reaction between two different metallic materials that are placed in direct contact.
