AbstractTo enhance the interface bonding of polyimide (PI)/carbon fiber (CF) composites, CFs were functionalized by introducing a polydopamine (PDA) transition layer, whose active groups provide absorption sites for the growth of molybdenum disulfide (MoS2) nanosheets and improve the bonding strength with PI. Uniform and dense MoS2 nanosheets with thicknesses of 30–40 nm on the surface of the PDA@CF were obtained via a subsequent hydrothermal method. As a result, the interface between the CF and the PI matrix becomes more compact with the help of the PDA transition layer and MoS2 nanosheets. This is beneficial in forming PI/CF-MoS2 composites with better thermal stability, higher tensile strength, and enhanced tribological properties. The lubricating and reinforcing effects of the hybrid CF-MoS2 in the PI composite are discussed in detail. The tensile strength of the PI/CF-MoS2 composite increases by 43%, and the friction coefficient and the wear rate reduce by 57% and 77%, respectively, compared to those of the pure PI. These values are higher than those of the PI/CF composites without MoS2 nanosheets. These results indicate that the CF-MoS2 hybrid material can be used as an additive to improve the mechanical and tribological properties of polymers.

How to significantly improve the mechanical and tribological properties of polyamide 46/polyphenylene oxide (PA46/PPO) alloy is an urgent but challenging issue. The PA46/PPO alloy reinforced with polyurethane-coated carbon fiber (PCF) was prepared and characterized. It was found that the mechanical properties, heat resistance, and tribological properties of PA46/PPO were greatly enhanced by incorporating PCF. When the composite containing 40 wt% of PCF, the tensile strength of the composite increased from 82 MPa to 282 MPa; meanwhile, volumetric wear was 0.56 mm3, which decreased by 95% in comparison with PA46/PPO. Scanning electron microscopy results showed that PCF had a good compatibility with the polymer matrix, due to good interfacial interaction between the PCF and the PA46/PPO. X-Ray photoelectron spectroscopy and laser Raman spectroscopy results further revealed that more graphitic carbon was microcracked to form a lubricating layer during friction process, thus remarkably improving the wear resistance of PA46/PPO.
