Development of high elastic and high repulsion type metal matrix composite materials and its application

1)高斥力型复合材料的制备采用在Ti-6Al-4V合金板之间插入100μm长的钨长纤维网和Ti-6Al-4V粉末，在10-2 Pa真空下热压的方法制备了W/Ti-6Al-4V复合材料。2）复合材料的评价试验（1）在复合材料的微观组织观察中，采用热压法将钨网与Ti-6Al-4V粉末紧密结合成型。结果表明，钨纤维保持了初始形状，没有发生变形，界面也很好。(2)当一个钨网插入复合材料中时，通过材料厚度检测到高排斥力。然后，恢复系数的增加被承认的板厚度减薄。(3)从复合材料弯曲试验的观察结果来看，击穿发生在钨网附近。这表明在钨表面上形成氧化膜的可能性。然而，为了有效地证明钨的拉伸能力，优选的是基体和钨之间的界面是松散的。3）有限元分析为了获得W/Ti-6A 1 -4V复合材料的最佳厚度，将其用于高尔夫球杆杆面，对钛合金与钨片复合的模型进行了有限元分析。(1)钨板和高尔夫球杆表面的厚度变化和分析。得到了位移分布。(2)验证了板厚与挠度之间的线性函数关系。通过使用钨，可以使高尔夫球杆面变薄，并获得具有高排斥特性的高尔夫球杆头的指示剂。

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.
