Abstract
Abstract The disclosure embraces a golf club head and method of producing same wherein the head is fashioned of laminations or layers of resinous or plastic materials bonded together to form an integrated or composite head or body wherein certain laminations or layers have particular characteristics and other laminations or layers have different characteristics, the laminations or layers having particular characteristics being preferably alternately oriented in assembly with the laminations or layers having different characteristics providing a golf club head which is dimensionally stable and of high durability and structural integrity and having high impact resistance at relatively the same density as a solid persimmon wood head.
