这项工作的目的是测试一种新的聚四氟乙烯浸渍布材料作为表面层上的液压马达的活塞在与凸轮滚子的接口。使用标准Bowden & Leben滑动摩擦测试仪进行测试，该测试表明，在干燥和润滑条件下，布材料给出与当前材料（PTFE浸渍的烧结青铜）类似的结果。在改进的双圆盘试验机上进行的实际部件试验表明，该布在减少润滑的条件下表现更好。需要进行磨损测试，以充分评估在液压马达中使用该材料的可行性。
The aim of this work was to test a new PTFE impregnated cloth material for use as a surface layer on the pistons of a hydraulic motor at the interface with the cam roller. Tests were carried out using a standard Bowden & Leben sliding friction tester which indicated that the cloth material gave similar results to the current material (PTFE impregnated sintered bronze) in both dry and lubricated conditions. Actual component tests run on a modified twin disc test machine showed that the cloth performed better in conditions of reduced lubrication. Wear testing would be required to fully assess the feasibility of using the material in a hydraulic motor.
