The friction and wear tests of the self lubricating bearing made of carbon fiber reinforced copper matrix composite materials are arranged by uniform design that can greatly reduce the test duration.

根据均匀设计原理，对碳纤维增强铜基复合材料的磨损试验参数予以科学排列，不仅减少了试验次数，而且提高了试验数据统计结果的可靠性。

At the same time, the turn-around ring of the hammer head is made of special composite material, with the qualities of wear-resisting, self - lubricating, non-maintaining, easy changing etc.

同时锤头回转圈采用特殊复合材料，具有耐磨、自润滑、免维护、易更换等特点。
