The strikeface and frame are formed from a thermoplastic composite comprising a thermoplastic polymer having a plurality of discontinuous fibres embedded therein. Each of the plurality of discontinuous fibres have a length of less than about 40 mm. The specific gravity of the thermoplastic can range between 1.0 and 2.0 and the thermoplastic composite is 20% to 70% fibres by volume. Also disclosed is a golf club head wherein the thermoplastic composite comprises fibres with a length in the range of 5mm to 12mm.

熱可塑性複合材料を含むゴルフクラブヘッド

【解決手段】ゴルフクラブヘッドは、前本体１２と、前本体に連結されて、間に中空キャビティを画定する後本体１４とを備える。前本体は、打球表面を画定する打撃面３０、ホーゼル３８、及び打撃面を少なくとも部分的に取り囲み、打球表面から離れるように打撃面の周辺から後方に延びるフレーム３４を備える。打撃面及びフレームは、複数の不連続繊維が内部に埋め込まれた熱可塑性ポリマーを含む熱可塑性複合物質から形成されている。複数の不連続繊維はそれぞれ約４０ｍｍ未満の長さを有し、打撃面の中心とホーゼルとの間では、複数の不連続繊維の約５０％超が、打撃面の中心からホーゼルまで延びる水平軸の平行の約３０°以内に整列している。【効果】軽量化しながら、衝撃力に耐えるのに必要な構造的一体性を提供する。多くの実施形態では、繊維補強熱可塑性複合物質は、金属材料で達成可能な比よりも大きい強度対重量比及び強度対弾性率比を含みうる。【選択図】図１

Multi-component golf club head

Co-molded golf putter with integral interlocking features

A co-moulded putter-type golf club head comprising a high-density chassis 1102 made of a first material and a low-density putter-type body 1104 made of a second material. The first material can be a high density metal e.g. steel or tungsten. The second material can be a low density thermoplastic composite e.g. polyphenylene sulphide (PPS) or polyamide (PA). The chassis comprises a heel portion 1124, toe portion 1126 and rear portion 1128 which together enclose a flow aperture 1138. The body portion encapsulates the chassis such that the body extends through and completely fills the flow aperture, including at least one interlocking feature 1120, to interlock the body and chassis, and thus form the club head. Other embodiments are described.

Mixed material golf club head

Described herein is a golf club head comprising a sheet composite midbody, a filled thermoplastic composite weight seating portion, and a removable weight. The weight seating portion can comprise a weight channel within which the weight can be repositioned to alter the fade or draw bias of the club head. The golf club head can further comprise a front body with a perimeter surrounding frame. The midbody can be connected to the front body. The weight seating portion can be co-molded to the midbody.

Golf club head with undercut and insert

The invention presented herein is directed to a back cavity insert for a cavity-backed iron-type golf club head. The rear perimeter of the iron-type golf club head and the rear surface of a strikeface cooperate to define a back cavity. The rear perimeter can comprise any edge or percentage of the perimeter of the back cavity. An insert may be placed into the back cavity such that the insert covers at least 60 percent to 100 percent of the strikeface rear surface area. When the insert is attached to the iron-type golf club head strikeface rear surface, it will interact with the iron-type golf club head strikeface when the strikeface deforms and rebounds. The insert thickness, composition, and stiffened outer surface may unduly restrain the deformation or flexing of the strikeface and reduce the amount of energy returned to the golf ball.
