项目摘要

1) Manufacturing of high repulsion type composite materialsW/Ti-6A1-4V composite materials were manufactured by the method which Tungsten long fiber mesh of 100μm in length and Ti-6A1-4V powder were inserted between Ti-6A1-4V alloy plates and they were hot pressed in the vacuum of 10-2 Pa. The composite materials of 10cm×10cm square which were more high density than the previous year were completed.2) Evaluation test of composite materials(1) In the minuteness organization observation of composite materials, Tungsten mesh and Ti-6Al-4V powder were closely molded by hot-press. It was find that Tungsten fiber maintained initial shape without transforming and interface was also excellent.(2) The high repulsion power was detected by the material thickness when one Tungsten mesh was inserted in composite materials. Then, the rise of the restitution coefficient was admitted as plate thickness thinned.(3) From the results of observation in the bending test of composite materials, the breakdown occurred from the Tungsten mesh neighborhood. This suggested the possibility that the oxide film was formed on the Tungsten surface. To demonstrate the tensile ability of Tungsten effectively, however, it is preferable that the interface between matrix and Tungsten was loose. This was good condition for the restitution coefficient was improved3) FEM analysisTo obtain the optimum thickness of W/Ti-6A1-4V composite materials, when the materials were used for the golf club surface, the model which titanium alloy was compound by Tungsten sheet was analyzed by FEM.(1) The thickness of Tungsten sheet and golf club surface were changed and analyzed. The distributions of displacement were obtained.(2) The relationship of the linear function was approved between the plate thickness and the flexure. By using Tungsten, it was possible to make golf club face thin and the indicator to golf club head with high repulsion characteristic was obtained.

1）高排斥型复合材料SW/TI-6A1-4V复合材料的制造是通过该方法制造的，该方法的长度为100μm，长度为100μm和TI-6A1-4V粉末插入TI-6A1-4V合金盘之间，并在10-2 PA的真空中加热了10-2 Pa。 2）复合材料的评估测试（1）在分钟的复合材料观察中，钨网格和TI-6AL-4V粉末被热压密切构成。发现钨纤维保持初始形状而没有转化，界面也非常好。（2）当将一个钨网插入复合材料中时，材料厚度检测到高排斥力。然后，将约束系数的升高作为板厚度变细。（3）从复合材料的弯曲测试中的观察结果中，分解发生在Tungsten网状邻域。这表明氧化膜在钨表面形成。但是，为了有效地证明钨的拉伸能力，首选矩阵和钨之间的界面松散。这是改善约束系数的良好状态。获得位移的分布。（2）在板厚度和弯曲之间批准线性函数的关系。通过使用Tungsten，可以使高尔夫球俱乐部的面孔变薄，并获得具有高排斥力特征的高尔夫球俱乐部头的指示器。
