A novel structural member, such as a tennis racket, and the method for making same, provides a high strength to weight ratio. The structural member of this invention consists of a fiberglass shell which surrounds a syntactic foam core. The fiberglass shell may be further selectively reinforced with a ribbon which is formed from a high strength fiber such as boron fibers, graphite fibers, aramid fibers, etc. Because the structure of this invention incorporates a high strength to weight ratio it can be utilized in the manufacture of rackets of conventional and radical design. This invention relates to a structural member consisting of a tennis racket having a high strength to weight ratio.

The subject invention relates to a golf ball having a cover which is completely or partially formed from a cellular polymeric material. By incorporating the subject invention into a golf ball structure, it is possible to selectively alter its 'feel' characteristics, the physical properties and flight characteristics. The subject invention can be utilized with golf balls having either solid or wound cores. The subject golf ball cover can be formed from a plurality of natural and synthetic polymeric materials. It is preferred that the golf ball cover be formed from ionic copolymers of polyolefins and unsaturated monocarboxylic acids wherein said ionomers incorporate zinc or sodium ions. Mixtures of said ionic copolymers may likewise be utilized.

Golf ball having cellular cover

A ski boot having an outer shell which is formed from a structural polymeric foam. The density of the foam may be uniform or it may vary throughout the cross-section of said outer shell. The foam likewise incorporates inner and outer skins which may or may not be impermeable.

Foamed ski boot

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.
