针对舰船艉轴密封摩擦副的载荷特点，采用碳纤维填充聚苯酯基复合材料制备出一种新型自润滑复合材料，在摩擦磨损试验机上研究其在干摩擦、水润滑和海水润滑条件下的摩擦磨损性能，并探讨其摩擦磨损机制。结果表明，在干摩擦条件下，复合材料的摩擦因数和磨损量较大，而在水润滑和海水润滑条件下的摩擦因数和磨损量明显下降，其中在海水润滑条件下的摩擦因数最低，磨损量最小，因此该复合材料在海水介质中作为密封环使用，满足舰船艉轴密封材料的使用条件。复合材料在干摩擦条件下磨损机制以疲劳磨损和黏着磨损为主，在水润滑条件下以黏着磨损为主，在海水润滑条件下以黏着磨损和腐蚀磨损为主。

According to the load characteristics of ship stern shaft sealing friction pairs, a new type of self-lubricating material of carbon fiber filled ekonol-based composites was prepared, its tribological behaviors were investigated in the friction and wear testing machine under dry sliding, water lubrication and seawater lubrication, and the tribological mechanism was discussed. The results show that under dry sliding ,the friction coefficient and wear mass loss are large for composites, and they are obviously decreased under water lubrication and seawater lubrication. Under seawater lubrication, the friction coefficient and wear mass loss are the lowest, therefore carbon fiber filled ekonol-based composites used as sealing ring can meet the requirement of ship stern shaft sealing materials under seawater lubrication. The tribological mechanism of the composites is main fatigue wear and adhesive wear under dry sliding, main adhesive wear under water lubrication, and main adhesive wear and corrosive wear under seawater lubrication.
