Abstract—

The tribomechanical properties of UPA-6130UV antifrictional polyamide composite filled with short carbon fibers have been studied in relation to metal-polymer bearings, gears, etc. The “pin-on-disc” setup was used to determine the macroscopic characteristics, and contact indentation and scratch testing, were employed to find submicroscopic parameters of the surface layer of this material before and after friction. It has been found that the tribological properties of studied carbon-filled polyamide are superior to those of glass-filled polyamide. With increase in the specific load, the mass wear of the UPA-6130UV composite increases less (from 0.0012 g at 10 MPa to 0.004 g at 40 MPa) and is significantly smaller than that of the PА6-L-SV30-1 glass-filled composite, the wear of which is 0.003 g at 10 MPa and 0.042 g at 40 MPa, respectively.

在干滑动摩擦期间的磨损测试前后，使用表面层的亚微观机械诊断来比较评估碳填充和玻璃填充的聚酰胺复合材料的摩擦学有效性

摘要-

研究了短碳纤维填充的 UPA-6130UV 减摩聚酰胺复合材料与金属聚合物轴承、齿轮等的摩擦力学性能。“销盘”装置用于确定宏观特性和接触压痕和划痕测试，用于发现摩擦前后该材料表面层的亚微观参数。研究发现，所研究的碳填充聚酰胺的摩擦学性能优于玻璃填充聚酰胺。随着比载荷的增加，UPA-6130UV复合材料的质量磨损增加较少（从10 MPa下的0.0012 g增加到40 MPa下的0.004 g），并且明显小于P-6-L-SV30-1玻璃纤维填充的磨损量复合材料的磨损量在 10 MPa 和 40 MPa 下分别为 0.003 g 和 0.042 g。
