Abstract
Description
本發明係有關於具有混合材料構造的高爾夫球桿頭。 The present invention relates to a golf club head having a mixed material structure.
一般而言,高爾夫球桿頭的整體性能取決於多項重要物理參數(例如容積、質量等等),而總質量即是高爾夫球桿頭最重要的物理參數。高爾夫球桿頭的總質量是總結構質量與總自由設置質量的總和。結構質量概指為使桿頭能夠耐受反覆撞擊所需結構彈性的材料質量。結構質量受設計所左右,因此設計人員在比質量分佈方面的掌控空間有限。反之,自由設置質量是可添加至桿頭設計而賦予球桿客製化性能及/或寬容度的一切額外質量(超過高爾夫球桿頭最低結構要求者)。此技藝中需要一種可以為所有金屬高爾夫球桿頭提供最大化自由設置重量以達成最大桿頭慣性矩(MOI)並將重心(CG)下移/後移的方式。 Generally speaking, the overall performance of a golf club head depends on a number of important physical parameters (such as volume, mass, etc.), and the total mass is the most important physical parameter of the golf club head. The total mass of the golf club head is the sum of the total structural mass and the total free setting mass. Structural quality refers to the material quality of the structural elasticity required for the club head to withstand repeated impacts. The quality of the structure is determined by the design, so designers have limited control space in terms of specific mass distribution. On the contrary, the freely set quality is all the extra quality that can be added to the club head design to give the club customized performance and/or latitude (that exceeds the minimum structural requirements of the golf club head). There is a need in this art to provide all metal golf club heads with a way to maximize the freedom to set the weight to achieve the maximum moment of inertia (MOI) and move the center of gravity (CG) down/back.
本發明提供一種高爾夫球桿頭,其係包含相互結合的混合材料後本體與金屬前本體,所述金屬前本體包含擊球面及周圍框架。混合材料後本體包含纖維加固式熱塑性複合材料彈性層、模製熱塑性結構層、金屬配重墊及固定在金屬配重墊內的金屬重物。混合材料後本體構造可大幅 減輕結構質量,有助於改善自由設置質量的分配,從而改善高爾夫球桿頭的MOI及CG。 The present invention provides a golf club head which includes a mixed material rear body and a metal front body that are combined with each other, and the metal front body includes a ball striking surface and a surrounding frame. The mixed material body includes a fiber-reinforced thermoplastic composite elastic layer, a molded thermoplastic structure layer, a metal weight pad, and a metal weight fixed in the metal weight pad. The body structure after mixing materials can be greatly Reducing the structural quality helps to improve the distribution of free setting quality, thereby improving the MOI and CG of the golf club head.

甲.擊球面A. Batting surface
參照圖5、6及9,高爾夫球桿頭100的前本體104包含一用於敲擊高爾夫球的擊球面120。擊球面120包含一中心點160、一高擊平面164及一中間平面168。中心點160與桿頭100的冠部112及底部116為等距,且與最靠近趾部128的面的邊緣及最靠近踵部124的擊球面120邊緣為等距。高擊平面164與桿頭100擊球面120的中心點160相切。高擊平面164與地面180交叉。
5, 6 and 9, the
桿頭100擊球面120的厚度是擊球面120與前本體104內表面170之間的距離。擊球面120的厚度在不同位置上各不相同,因此定義可變擊球面厚度(VFT)或可變厚度輪廓196。可變厚度輪廓196具有一中央區域192及一周邊區域188。在許多實施例中,可變厚度輪廓196的中央區域192為橢圓形、卵形或蛋形。中央區域192概呈橢圓形狀,且自是擊球面120靠
近底部116及踵部124的部分延伸到擊球面120靠近該趾部128及冠部112的部分。
The thickness of the
參照圖6,中央區域192延伸跨越或位於或接近擊球面120的中心點160,使得擊球面120中心點160位於中央區域192內。中央區域192包含擊球面120的最大厚度。在許多實施例中,中央區域192的厚度實質上維持一致。周邊區域188位於擊球面120外周140的周圍且包含擊球面120的最小厚度。在許多實施例中,周邊區域188的厚度實質上維持一致。擊球面120在中央區域192內的厚度大於擊球面120在周邊區域188內的厚度。過渡區域190位於中央區域192與周邊區域188之間。過渡區域190包括變化厚度,在中央區域192與周邊區域188之間產生過渡。
Referring to FIG. 6, the
此外,擊球面120的長軸184概延伸於踵部124到趾部128方向。長軸184與中心點160相交,且與地面形成一角度β。在許多實施例中,長軸184反映中央區域192的橢圓形狀。
In addition, the
長軸184與地面180形成的角度約為20度。例如,形成於中央區域192長軸與地面180之間的角度可為0至60度。在某些實施例中,形成於中央區域192長軸184與地面180之間的角度可為2至20、2至30、5至40、10至50或15至60度。在其他實施例中,長軸184與地面180之間的角度可為5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24、25、26、27、28、29、30、31、32、33、34、35、36、37、38、39、40、41、42、43、44、45、46、47、48、49、50、51、52、53、54、55、56、57、58、59或60度。中央區域192具有角度傾向可致使蛋形的縱長部分朝向擊球面120的趾部上方CT值高的部分延伸,藉此改善擊出的球速。
The angle formed by the
橢圓或卵形或蛋形,連同可變厚度輪廓196中央區域192的角度,可使擊球面120的加厚區域位於CT本身較高的區域,且使擊球面120的減薄區域位於CT本身較低的區域。據此,擊球面上CT本身較高的區域會減少,且CT本身較低的區域會增加,致使整個擊球面120的CT常態化。在許多實施例中,可變厚度輪廓196使得特徵時間小於115微秒(μs)、小於110μs、小於105μs、小於100μs、小於95μs、小於90μs或小於85μs的。再者,在許多實施例中,可變厚度輪廓40使得平均特徵時間大於230μs、大於235μs或大於240μs。例如,在許多實施例中,面板20的平均CT可為230μs至240μs、235μs至240μs或240μs至245μs。
The ellipse or oval or egg shape, together with the angle of the
再者,VFT的角度是設計將擊球面120的加厚區域放置在所需位置,因此相較於不具有上述可變厚度輪廓196的擊球面,擊球面120可減輕重量。額外自由設置重量可重新導入於桿頭的其他區域,以調整桿頭重心位置並增加桿頭慣性矩,從而改善桿頭性能。與不具可變厚度輪廓196的類似桿頭比較,圖示實施例中具有可變厚度輪廓196的桿頭100,如在此所述者,可省下2.1公克的重量。
Furthermore, the angle of the VFT is designed to place the thickened area of the
乙.插鞘B. Hose
高爾夫球桿頭100前本體104包含該插鞘144。插鞘144包括一沿插鞘144孔洞中心延伸的插鞘軸176。參照圖3及6,於本實例中,高爾夫球桿頭100的插鞘耦接機構包含該插鞘144及一軸套(圖未示),軸套可耦接於高爾夫軸桿(圖未示)末端。軸套可以多種配置方式耦接於插鞘144,藉此使得高爾夫軸桿能夠相對於插鞘軸176以多種角度固定至插鞘144。但在其他
實例中,軸桿可能是以無法調整的方式固定於插鞘144。在圖示實施例中,從該高爾夫球桿頭10前視圖(圖1)來看,插鞘軸176與地面12夾設一角度α。圖中所示角度α為約60度,但在其他構造中,該角度α可為約40至80度(例如約40度、約45度、約50度、約55度、約60度、約65度、約70度、約75度或約80度)。
The
此外,插鞘軸176與長軸184夾設一角度θ。在許多實施例中,形成於插鞘軸176與長軸184之間的角度θ可為60及140度。在多數實施例中,形成於插鞘軸176與長軸184之間的最小角度θ為約60度。在某些實施例中,形成於插鞘軸176與長軸184之間的角度θ可為60至70度、70至80度、80至90度、90至100度、100至110度、110至120度、120度至130度或130至140度。在一實施例中,形成於插鞘軸176與長軸184之間的角度θ可為80度至90度。
In addition, the
丙.周圍框架C. Surrounding frame
高爾夫球桿頭100前本體104的周圍框架136是自擊球面120的整個外周140向後延伸。周圍框架136更包含一可經操作而將前本體104與後本體108耦接的凸緣174。
The surrounding
凸緣174提供一可供後本體108連接而實現搭接的表面。凸緣174自該整個周圍框架136向後延伸,且形成階梯狀結構,自周圍框架136外表面172下降。在許多實施例中,前本體104凸緣174的作用是供後本體部分重疊於凸緣174上後經由環氧化物、黏貼、焊接、黏合、雷射輔助金屬塑膠焊接、硬焊或任何其他適合的連接方法而結合至前本體104。利用搭接式凸
緣174則無需使用任何機械式緊固件即可確保前本體104與後本體108穩固配接。
The
此外,周圍框架136包含外表面172及內表面170,可設置額外空氣動力特徵以改善高爾夫球桿頭的整體速度。高爾夫球桿頭100前本體104的周圍框架136可包括額外空氣動力特徵,例如湍流器200。所述湍流器200可用於減少桿頭阻力並增加球桿100速度。美國專利第9,555,294號對於湍流器200即有詳細敘述,此前案的整體經參照而包含於本文。
In addition, the surrounding
二、後本體Second, the back ontology
參照圖4及圖8至13,桿頭100後本體108包含一冠部件204、一底部件208及一配重墊212。冠部件204及底部件208結合為一體以形成高爾夫球桿頭100冠部112及底部116的一部分。當前本體104與後本體108結合時,前本體104的外表面172、冠部件204及底部件208形成高爾夫球桿頭100的整個冠部112及底部116。後本體108的底部件208可進一步包含一複合材料彈性層152、一複合材料結構層156及一金屬配重墊212。
4 and FIGS. 8 to 13, the
在本設計中,後本體108可包括模製熱塑性材料(例如射出成形熱塑性材料)與纖維加固式熱塑性複合材料的混合。如在此所用,模製熱塑性材料是仰賴聚合物本身來為最終組件提供結構及剛性。模製熱塑性材料則是透過例如射出成形等模製成形技術,使材料在加熱至超過聚合物熔點的溫度時呈現自由流動狀態。經混入填充材料的模製熱塑性材料稱為填料式熱塑性(FT)材料。填料式熱塑性材料在加熱/融化狀態下可自由流動。為促進流動特性,填充材料大致包括最大維度小於約25毫米,或更常見者
為小於約12毫米的分離微粒狀物質。例如,填充材料可包括最大維度為4毫米、5毫米、6毫米、7毫米、8毫米、9毫米或10毫米的分離微粒狀物質。適合用於本設計的填充材料可為例如玻璃珠或由碳、玻璃或芳香族聚醯胺聚合物所構成的非連續性加固纖維。
In this design, the
對比於模製及填料式熱塑性材料,纖維加固式複合材料(FRC)材料通常包括一或多層延伸跨越聚合物大部分面積的單向或多向纖維布料。與用在FT材料中的加固纖維不同,FRC中所用纖維的最大維度可能更大/更長,且具有足夠的大小及特性,使其可成為與聚合物分離的連續布料。當與熱塑性聚合物一起成形時,即使聚合物已經融化而呈流動狀時,其中所包含的連續纖維通常也不會流動。 In contrast to molded and filled thermoplastic materials, fiber-reinforced composite (FRC) materials generally include one or more layers of unidirectional or multidirectional fiber fabrics that extend across most of the polymer area. Unlike the reinforcing fibers used in FT materials, the maximum dimensions of the fibers used in FRC may be larger/longer, and have sufficient size and characteristics to make it a continuous fabric separated from the polymer. When molded together with a thermoplastic polymer, the continuous fibers contained therein usually do not flow even when the polymer has melted and becomes fluid.
FRC材料的成形方式通常是先將纖維設置成所需排列,而後使纖維材料吸入足量而可使其產生剛性的聚合物材料。以此方式,FT材料的樹脂含量可大於約45%體積比或更佳的是大於約55%體積比,而FRC材料的樹脂含量宜小於約45%體積比,或更佳的是小於約35%體積比。傳統上FRC材料的聚合物基質是雙劑型熱固性環氧化物,但也可使用熱塑性聚合物來做為基質。在許多情況下,會在最終製造前預先製備FRC材料,而這種中間材料通常稱為預浸體。若使用熱固性聚合物,則預浸體是部分固化為中間型態,待預浸體形成為最終形狀時再進行最終固化。若使用熱塑性聚合物,則預浸體可包括冷卻的熱塑性基質,隨後再接受加熱並模製成最終形狀。此一技術可用來製造像是後本體108這樣複雜且輕量的幾何形狀,但不會犧牲強度。
The forming method of FRC materials is usually to arrange the fibers in the required arrangement first, and then make the fiber material suck in enough to make it produce a rigid polymer material. In this way, the resin content of the FT material can be greater than about 45% by volume or more preferably greater than about 55% by volume, while the resin content of the FRC material is preferably less than about 45% by volume, or more preferably less than about 35 %Volume ratio. Traditionally, the polymer matrix of FRC materials is a two-component thermosetting epoxy, but thermoplastic polymers can also be used as the matrix. In many cases, FRC materials are prepared in advance before final manufacturing, and this intermediate material is often called a prepreg. If a thermosetting polymer is used, the prepreg is partially cured into an intermediate shape, and the final curing is performed after the prepreg is formed into the final shape. If a thermoplastic polymer is used, the prepreg may include a cooled thermoplastic matrix, which is then heated and molded into the final shape. This technique can be used to manufacture complex and lightweight geometric shapes such as the
甲.冠部件A. Crown parts
後本體108包含冠部件204。參照圖4及圖9,冠部件204包含一外表面206,因此當後本體108與前本體104接合時,冠部件204的外表面206與周圍框架136的外表面172形成高爾夫球桿頭100的整個冠部112。冠部件204外表面206概呈相對於地面180凹入的曲線形狀。當將冠部件整個放置於前本體104的凸緣174上時,冠部件204的曲線形狀使得後本體208可以無縫接合於前本體104。
The
在許多實施例中,冠部件204是由碳纖維織物構成,沒有任何複合材料夾層或單向複合材料夾層。在一實施例中,製作冠部件204的成形纖維加固式複合材料中可包含內嵌於聚合物基質中的編織玻璃或碳纖維加固層。在此種實施例中,聚合物基質較佳的是熱塑性材料例如聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺,例如PA6或PA66。在其他實施例中,冠部件204的材質可為其中嵌設有玻璃珠或不連續玻璃、碳或芳香族聚醯胺聚合物纖維填料的填料式熱塑性材料,其基本的熱塑性材料可為,例如,聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺。在其他實施例中,冠部件204可採用兼具填料式熱塑性材料及成形纖維加固式複合材料的混合材料構造。
In many embodiments, the
乙.底部件B. Bottom part
後本體108包含底部件208。參照圖4及9,底部件208包含結構層156及彈性層152,提供輕量但堅固的高爾夫球桿頭100底部116。彈性層152與地面180相切,而結構層156是位於彈性層152頂部上,且在高爾夫球桿頭100的內部。
The
在一實施例中,底部件208的混合材料構造兼具纖維加固式熱塑性複合材料彈性層152及模製熱塑性結構層156。在一較佳實施例中,模製熱塑性結構層156可使用填料式熱塑性材料形成,此填料式熱塑性材料是在例如聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺(例如PA6或PA66)等熱塑性材料中嵌入玻璃珠或不連續玻璃、碳或芳香族聚醯胺聚合物纖維填料而成。所述彈性層152可包含內嵌於熱塑性聚合物基質中的編織玻璃、碳纖維或芳香族聚醯胺聚合物纖維加固層,所述熱塑性聚合物基質包括,例如,聚苯硫醚(PPS)、聚醚醚酮(PEEK)或聚醯胺,例如PA6或PA66。在一特定實施例中,冠部件202及彈性層152可各包含內嵌於聚苯硫醚(PPS)中的編織碳纖維布料,且該結構層156可包含一填料式聚苯硫醚(PPS)聚合物。
In one embodiment, the mixed material structure of the
結構層156可大致包括一前部236及一定義底部件208外周的外周部240。桿頭100組裝完成時,前部236是結合於該金屬前本體104,且外周部240是結合於冠部件204。結構層156具有複數個位於外周之內的孔洞244,各自延伸通過結構層156的厚度。再者,結構層156可包括一或個多結構件248,其係自該前部236延伸於至少兩個上述孔洞244之間。此外,如下所述,結構層156可配置為包含一金屬配重墊212及金屬重物220。
The
彈性層152可結合於該結構層156而直接抵頂或覆蓋前部236、外周部240及複數結構件248的至少一部分。藉此,從桿頭100外部來看,彈性層152可完全涵蓋各該複數孔洞244。同樣,彈性層244的內部可含有一或多個結構件248做為選擇性的加固結構,類似於加強肋或角板。
The
關於冠部件204及底部件208兩者的聚合物構造,所用的填料式熱塑性材料或纖維加固式熱塑性複合材料宜包含一或多種具有足夠材料
強度及/或強度/重量比特性而能耐受通常使用,同時有助於減輕設計重量的工程聚合物。具體而言,高爾夫球桿頭100的材料必須能夠有效耐受因擊球面120與高爾夫球之間撞擊而產生的應力,並且不會造成高爾夫球桿頭100總重實質增加。整體而言,較佳的聚合物應具有大於約60MPa(純聚合物)的降伏抗拉強度,且當含有填料時,其降伏抗拉強度大於約110MPa,或更佳的是大於約180MPa,又更佳的是大於約220MPa。在某些實施例中,適合的填料式熱塑性聚合物可具有約60MPa至約350MPa的降伏抗拉強度。在某些實施例中,這些聚合物在填料及非填料狀態下的密度可為約1.15至約2.02,且熔化溫度較佳的是大於約210ºC,或更佳的是大於約250ºC。
Regarding the polymer construction of both the
丙.配重墊C. Weight pad
參照圖4及圖9-11,在許多實施例中,結構層156可包括一配重墊212。配重墊212包含一可用於容納金屬重物220的凹腔216。在某些實施例中,配重墊212概朝向桿頭100的最後端點設置,因此可整合及/或直接耦合於結構層156後部132。在某些實施例中,彈性層152可具有孔洞或開口252,以供配重墊212的一部分延伸通過其中。在某些實施例中,上述開口250與前本體104相隔一至少25毫米或至少30毫米或至少35毫米(沿桿頭外表面測量)的最小距離。如圖9所示,組裝完成時,配重墊212的外表面可與直接毗鄰的底部件208及/或彈性層152外表面齊平。以此方式,配重墊212的一部分可形成高爾夫球桿頭100外側底部116的一部分。此外,在某些實施例中,配重墊212的內表面可暴露於球桿頭的內部。配重墊212的作用是提供密集的向後質量以改善高爾夫球桿頭的整體MOI。由於複合材料後本體108
大幅減輕重量,因此自由設置質量可集中放置在配重墊212及重物220所在的區域。
4 and 9-11, in many embodiments, the
配重墊212可包含任何所需形狀,盡可能使最多質量放置在高爾夫球桿頭100後部132的外周。配重墊212形狀可為以下任一者:圓形、三角形、方形、矩形、梯形、五邊形、曲線、桃形或任何其他多邊形或具有至少一個彎弧表面的形狀。在一實施例中,配重墊212可概呈梯形。在另一實施例中,配重墊212可略呈矩形。此外,在另一實施例中,配重墊212可略呈圓形。又或者,在另一實施例中,配重墊212可略呈三角形。
The
在多數實施例中,配重墊212可為金屬材質,因而能夠提供密集的向後部分以改善高爾夫球桿頭100的整體MOI。在某些實施例中,配重墊212的材質可為不鏽鋼、鈦、鋁、鋼合金(例如455鋼、475鋼、431鋼、17-4不鏽鋼、馬釘鋼)、鈦合金(例如Ti 7-4、Ti 6-4、T-9S)、鋁合金或複合材料。在一實施例中,配重墊212可為不鏽鋼。配重墊212可經鍛造或鑄造製成,而後再固定於後本體108的底部件208內。
In most embodiments, the
配重墊212是經由一或多種可提供牢固結構結合的技術而固定在彈性層152中的開口250內。由於材料種類/材料表面能有所差異,加上組件質量與接觸表面積比較高,單純使用習知黏膠可能難以耐受高爾夫球桿撞擊高爾夫球期間產生的力量。為解決此一問題,可利用封裝配重墊的至少一部分來將配重墊的至少一部分整合於結構層156及/或彈性層152。如此一來,封裝層的材料強度可帶來較單獨使用表面黏膠更耐久可靠的結合效果。參照圖9及13,適合的封裝方式可包括以結構膠帶261包覆配重墊212的邊緣252、直接將配重墊的至少一部分212包裹在結構層156內或是將配重
墊的一部分包裹在彈性層152的相鄰夾層之間。上述技術可替代或搭配使用在配重墊與底部件208之間的化學黏膠。
The
在一種配置中,配重墊212可附加至底部件208而不使用任何機械式緊固件。在一實施例中,配重墊212為鑄造而成,且結構層156是經由例如埋入射出成形或共模技術而成形在配重墊212的至少邊緣252處。如上所述,結構層156的填料式熱塑性構造能夠形成複雜幾何形狀並以具有結構穩定性的方式圍繞邊緣延伸,因此特別適合用以承接配重墊212。取決於配重墊的幾何形狀,此種連接技術可能較難利用固定形狀的膠帶或FRC來實現。
In one configuration, the
配重墊212凹腔216自配重墊212向內延伸。在圖示實施例中,凹腔216為圓形。在其他實施例中,凹腔216可包含任何形狀。例如,凹腔216形狀可包含圓形、橢圓形、三角形、矩形、八邊形或任何其他多邊形或具有至少一個彎弧表面的形狀。凹腔216形成一個可供金屬重物220固定於其中的陷槽。金屬重物220可對高爾夫球桿頭100添加自由設置重量,藉此進一步改善高爾夫球桿頭100的MOI及CG。此外,透過凹腔216及金屬重物220的設置,不同密度的不同金屬重物可活動附加於高爾夫球桿頭100以改變其整體重量。
The
凹腔212的深度是從凹腔212基底224沿概與基底224垂直的方向而測量至底部件208外輪廓。在許多實施例中,凹腔212深度是介於0.10英吋及0.50英吋之間。在某些實施例中,凹腔212深度小於0.50英吋、小於0.45英吋、小於0.40英吋、小於0.35英吋、小於0.30英吋、小於0.25英吋、小於0.20英吋或小於0.15英吋。
The depth of the
再者,凹腔212包含位在基底224中的孔洞228。孔洞228自凹腔212基底224往內朝向高爾夫球桿頭100冠部112延伸。在某些實施例中,孔洞228可包含與緊固件230螺紋相配的螺紋,以便將金屬重物220固定在凹腔216內。在其他實施例中,孔洞228可不具有螺紋,而是搭配自攻或自鑽緊固件使用。
Furthermore, the
金屬重物220可在配重墊212的凹腔216中設置定位。在圖示實施例中,重物220為圓形以對應凹腔212的形狀。在其他實施例中,重物220可包含任何對應於凹腔212形狀的幾何形狀(例如圓形、橢圓形、三角形、矩形、梯形、八邊形或任何其他多邊形或具有至少一個彎弧表面的形狀)。
The
金屬重物220更包含一延伸通過整個重物220的孔洞232。所述孔洞232實質上具有與凹腔212孔洞228相仿的大小,且當重物是放置於凹腔212內時,重物220的孔洞232是與凹腔212的孔洞228對齊。在多數實施例中,孔洞232不具有螺紋,以供緊固件230通過重物220後經由螺紋固定於配重墊212的孔洞228。此外,在某些實施例中,可在凹腔212內先設墊片214,而後再將金屬重物220放置於凹腔212中。

圖14描繪一實施例中高爾夫球桿頭100的製造方法300,此桿頭具有一體結合的彈性層152、結構層156及底部件208的金屬配重墊220。所述方法300包含在步驟310將一纖維加固式熱塑性複合材料熱成形為桿頭100的外殼部。熱成形程序可涉及,例如,將熱塑性預浸體預先加熱到至少高於該熱塑性聚合物玻璃轉化溫度的成形溫度、使該預浸體成形為殼部形
狀而後將成形的零件修整為適當大小。

待複合材料殼部構成適當形狀後,在步驟320中,便可透過射出成形方式,使填料式聚合物支撐結構直接接觸殼體。此一工序通常稱為埋入成形。在此工序中,殼體是直接放置在加熱的模具內,此模具設有一暴露於部分殼體的帶閘凹腔。將熔化的聚合物強制注入凹腔,使其直接與加熱後複合材料殼體的熔化狀態聚合物混合,或使其局部與呈軟化狀態的殼體黏結。待模型冷卻,複合材料殼體及支撐結構的聚合物共同硬化而構成熔接關係。若殼部的聚合物及支撐結構的聚合物彼此相容,結合效果更佳,而若上述兩種組件包含共用的熱塑性樹脂組件,則結合效果又更進一步。雖然埋入成形是形成該結構的較佳技術,但亦可使用其他模製成形技術,例如壓縮成形。
After the composite shell has a proper shape, in
續參照圖14,經由步驟310及320形成底部件208之後,可將FRC冠部件204結合於底部件208以實質完成後本體108的結構(步驟330)。在一較佳實施例中,冠部件204的材質可為熱塑性FRC材料,並利用類似於步驟310所述的熱成形技術而構成所需形狀。以熱塑性複合材料製成的冠部件204可透過局部焊接技術結合於底部件208。上述焊接技術可為例如雷射焊接或超音波焊接,若該聚合物具有導電性,亦可使用電阻焊接。若冠部件204是以熱固性聚合物形成,則可利用例如黏膠或機械性固定技術(柱螺栓、螺絲、螺釘、機械性干涉嚙合等等)將冠部件204結合於底部件208。

繼而在步驟340中,可將包含固定後冠部件204及底部件208的後本體108黏結於金屬前本體104。雖然黏膠可以固定多數金屬,但可能需要使用一或多種助黏劑或表面處理來加強黏膠與後本體108聚合物之間
的結合。

三、優點3. Advantages
利用混合材料後本體構造可大幅減輕結構重量,且無需犧牲任何設計靈活性,並提供一種重新導入自由設置質量的可靠方式。雖然此種設計可完全使用填料式熱塑性材料,例如聚苯硫醚(PPS),製成如上所述,但使用纖維加固式複合材料則能夠在連續外表面上提供更強且更輕的構造。反之,全FRC設計無法輕易納入重物承接結構,因此無法輕易利用於增加自由設置質量。 The body structure using mixed materials can greatly reduce the structural weight without sacrificing any design flexibility, and provides a reliable way to re-import freely setting quality. Although this design can be made entirely of filler-type thermoplastic materials, such as polyphenylene sulfide (PPS), as described above, the use of fiber-reinforced composite materials can provide a stronger and lighter structure on a continuous outer surface. On the contrary, the full FRC design cannot be easily incorporated into the heavy object receiving structure, so it cannot be easily used to increase the free setting quality.
擁有金屬配重墊的混合材料高爾夫球桿頭較未設有金屬配重墊者的優勢在於,所述金屬配重墊可供變化及更換金屬重物,同時提供耐久可靠的金屬重物裝設位置。相較於未設有金屬配重墊的高爾夫球桿頭,金屬配重墊可耐受加掛重物時作用在配重墊上的扭力。再者,金屬配重墊可供製造商透過更換金屬重物而調整製造公差(亦即使整體桿頭的理想揮桿重量在206公克至209公克之間變化),或因應顧客需求規格而調整(例如高爾夫球員可使其桿頭加重,206公克至209公克)。 The advantage of a hybrid golf club head with a metal weight pad over those without a metal weight pad is that the metal weight pad can be used for changing and replacing metal weights, while providing durable and reliable metal weight installation position. Compared with a golf club head without a metal weight pad, the metal weight pad can withstand the torsion force that acts on the weight pad when a weight is added. Furthermore, the metal weight pad allows manufacturers to adjust manufacturing tolerances by replacing metal weights (even if the ideal swing weight of the overall club head varies from 206 grams to 209 grams), or to adjust to customer specifications ( For example, golfers can make their club head heavier, 206 grams to 209 grams).
