    • A golf club is provided having improved playing characteristics based upon a multiple material construction. This construction involves a club body in combination with a face insert that defines a hollow channel therebetween. This hollow channel is substantially filled with a heterogeneous viscoelastic material, such as urethane containing tungsten powder. The heterogeneous material is formulated such that the density of the material is varied based upon the location of that material within the hollow channel of the golf club head. In particular, lower density portions of the material are located near the top of the club head, and higher density portions are located near the bottom or sole of the club head. This moves the center of gravity of the club head downward and rearward, yielding improved feel and improved weight distribution and enhancing performance of the club.
    • 提供了一种基于多种材料构造具有改进的演奏特性的高尔夫球杆。 这种结构涉及与面部插入物组合的球杆体,其在它们之间限定中空通道。 该中空通道基本上填充有异质粘弹性材料,例如含有钨粉的氨基甲酸酯。 非均质材料被配制成使得材料的密度基于该材料在高尔夫球杆头的中空通道内的位置而变化。 特别地,材料的较低密度部分位于球杆头的顶部附近,并且较高密度部分位于球杆头的底部或底部附近。 这使得球杆头的重心向下和向后移动,产生改善的感觉和改善的重量分布并提高球杆的性能。
