改性玄武岩纤维/聚酰亚胺复合材料的摩擦磨损性能
Friction-wear Performance of Modified Basalt Fiber/Polyimide Composites
摘要
Abstract
Graphene oxide(GO)and silica nanoparticles(SiO2NPs)were introduced onto the surface of basalt fibers(BF)using the electrostatic self-assembly method.The SiO2NPs-modified composites(SiO2NPs-BF/PI)and the GO-SiO2NPs-modified composites(GO-SiO2NPs-BF/PI)were prepared using the thermal pressing method.A comparative study was conducted on the microstructural,mechanical,and tribological properties of the composites,and the corresponding wear mechanisms were discussed.The results show that introducing SiO2NPs and GO-SiO2NPs surface modification on BF significantly enhances the interfacial adhesion strength between BF and the PI matrix,thereby improving the mechanical performance of the composites.The Vickers hardness,compressive strength,three-point bending strength,and tensile strength of the SiO2NPs-BF/PI composite increases by 8.96%,15.77%,16.30%and 12.96%compared to the BF/PI composite.For the GO-SiO2NPs-BF/PI composite,the Vickers hardness,compressive strength,three-point bending strength and tensile strength were improved by 22.76%,28.16%,29.32%and 23.35%in comparison with the BF/PI composite.After 60 minutes of friction against GCr15 balls,the average friction coefficients of the SiO2NPs-BF/PI and GO-SiO2NPs-BF/PI composites decreased by 9.55%and 11.82%compared to the BF/PI composite.The wear rates were 0.618×10-5 mm3/(N·m)and 0.569×10-5 mm3/(N·m),respectively,which were 29.37%and 34.97%lower than that of the BF/PI composite.关键词
