Replacing the traditional self-lubricating fabric composites with new type of wear-resistant composite reinforced by warp-knitted fabrics PTFE-Nomex and PTFE-Nomex/Nomex (self-lubricating fiber: PTFE, reinforcing fiber: Nomex), in which the hybrid graphite/graphene particle modified phenolic is used as the adhesive resin. The influence of the fabric structure on the friction and wear properties of self-lubricating fabric composites was evaluated by the ball-on-disk and bearing friction tests. And the wear mechanism of the composites was investigated through scanning electron microscopy (SEM) and mechanical tests. The ball-on-disk friction test shows that the friction and wear properties of two kinds of composites with different structures are different with the increase of friction distance. In addition, the self-lubricating warp-knitted composite materials were prepared as self-lubricating joint bearing liners to evaluate the bearing application. It is proposed that the wear resistance of the two kinds of warp-knitted composites is poor, and the single layer is slightly better. It is related to the friction mode, mechanical and bonding properties of the bearing liners.

Friction And Wear Properties

In this study, the effects of nano-[Formula: see text] and carbon nanotubes on the friction and wear properties of carbon-epoxy woven composites have been explored. The unfilled carbon fabric composites and carbon fabric composites filled with carbon nanotubes and nano-[Formula: see text] were fabricated by vacuum infusion process. The worn surfaces were examined and possible wear mechanisms of unfilled and filled carbon fabric composites were discussed. In addition, the friction coefficient curves of unfilled and filled carbon fabric composites were analyzed and compared. The experimental results showed that either of the two nano-particles improved the friction coefficient and wear rate of carbon fabric composites; however, better improvement was observed for nano-SiO2. By adding these nano-particles to unfilled carbon fabric composites, a primary steady-state period with a low friction coefficient appeared in the friction coefficient curve of the composites, which indicates enhancement in bonding strength between carbon fiber and epoxy matrix due to the interfacial reinforcing action of the nano-particles.

Based on actual working conditions and parameters of the hydraulic steering gear, the purpose is optimizing the rubber seal of steering gear by different rubbers mixing technology. Compare the five kinds of rubber with metal of the friction characteristics in dynamic fit, it can obtain a performance excellent rubber real in the specific operation conditions. And then improve the overall service life of the steering gear. It is first prepared the same hardness TPU and PVC and blends that the ratio is 3:7, 5:5and7:3 in this article. The pros and cons of the five rubbers are analyzed in friction and wear properties of the above experimental. The test curve of coefficient friction and wear with time has been done under different load at constant low speed. It determines TPU/PVC = 3:7 blends through friction and wear and wear mechanism of five rubbers with steel comparatively analyses, and the heat resistance and wear resistance of them are better than the other TPU/PVC blends and PVC under oil lubrication conditions.
