    • Golf clubs, clubheads for golf clubs, and methods for making clubheads are disclosed. An exemplary clubhead includes a rear component and a front component affixed to the rear component. The rear component is made at least partially of a FeAlMn alloy having a density in a range of 6.2 to 7.2 g/cm3. The front component includes at least a portion of the face of the clubhead and is made of a material other than the FeAlMn alloy used to make the rear component. For example, the FeAlMn alloy contains (by weight) maximally 1% C, 27-32% Mn, 6-10% Al, 3-5% Cr, maximally 1% Si, and the balance being Fe. The reduced density of the rear component, compared to the density of conventional iron-type clubheads, provides more discretionary mass for manipulation in the clubhead, without sacrificing performance of the face of the clubhead.
    • 公开了高尔夫球杆,高尔夫俱乐部的杆头,以及制作球棒头的方法。 示例性的杆头包括后部部件和固定到后部部件的前部部件。 后部部件至少部分地由密度在6.2至7.2g / cm 3范围内的FeAlMn合金制成。 前部件包括杆头的表面的至少一部分,并且由用于制造后部件的FeAlMn合金以外的材料制成。 例如,FeAlMn合金含有最大1%C,27-32%Mn,6-10%Al,3-5%Cr,最大1%Si,余量为Fe。 与常规铁型杆头的密度相比,后部部件的密度减小,在球杆头的操作性方面提供了更多的自由裁量的质量,而不会牺牲球杆头的表面的性能。

    • The present disclosure pertains to composite articles, and in particular a composite face plate for a golf club-head, and methods for making the same. In certain embodiments, a composite face plate for a club-head comprises a lay-up of multiple, composite prepreg plies. The face plate can be made by first forming an oversized lay-up of multiple prepreg plies having a central portion and a sacrificial portion surrounding the central portion. The lay-up is at least partially cured in a mold under elevated pressure and heat. The lay-up is then removed from the mold and the sacrificial portion is removed from the central portion to form a composite part that is substantially free of defects.
    • 本公开涉及复合制品,特别是用于高尔夫球杆头的复合面板及其制造方法。 在某些实施例中,用于球杆头的复合面板包括多个复合预浸料层的叠层。 面板可以通过首先形成具有中心部分和围绕中心部分的牺牲部分的多个预浸料层的超大堆叠而制成。 叠层在模具中至少在高压和高温下至少部分固化。 然后从模具中取出叠层,并且将牺牲部分从中心部分移除以形成基本上没有缺陷的复合部件。
