Thermosetting phenolic aldehyde resin plastic alloy is a kind of composite consisted of thermosetting phenolic aldehyde resin, cotton fiber and carbon fiber, and it has many outstanding physical and mechanical performances, which makes it widely applied in underwater sliding bearing. The water lubricated bearing made of this kind of plastic alloy has a great bearing capacity and excellent tribological performance. In this paper, the effects of load, speed, and time on friction coefficient and wear rate of bearings, which are made of thermosetting phenolic aldehyde resin plastic alloy and lubricated by water with various sand contents, were studied using a MPV200 model friction and wear testing machine, and the characteristic of friction and wear was found out. At the same time, wear mechanisms were analyzed systematically. It provides a theoretical basis for practical application of water lubricated plastic alloy bearings.
