摘要:

高强度的聚合物材料具有优异的力学性能和耐磨特性,作为新一代轴瓦材料,其广泛应用于水泵、水电发电机组等领域。通过短切碳纤维(CF)与聚氨酯弹性体(PUE)复合,制备了一种高性能聚氨酯弹性体/碳纤维(PUE/CF)复合材料,探究了CF质量分数对复合材料的力学性能和摩擦学性能的影响。结果表明,该复合材料的硬度可达到60~68 HD,拉伸强度和断裂伸长率分别为54 MPa和298%,干摩擦条件下摩擦系数和磨损率分别为0.16和0.570%,水润滑条件下摩擦系数和磨损率分别为0.02和0.129%。因此,该材料可以满足聚合物轴瓦材料的应用需求,在汽车、船舶等领域具有广阔的应用前景。

Abstract:

Highstrength polymer materials with excellent mechanical properties and wear?resistance have been widely used in water pumps, electric generator and other fields as a new generation of bearing materials. A high performance polyurethane/carbon fiber composite (PUE/CF) was prepared by combining chopped carbon fiber (CF) with polyurethane elastomer (PUE), and the effects of carbon fiber content on the mechanical and tribological properties of the composites were investigated. The results show that the hardness of the composite can reach 60 ~ 68 HD, the tensile strength and elongation at break can reach 54 MPa and 298% respectively. Under dry friction condition, 0.16 of friction coefficient and 0.570% of wear rate can be obtained. Under water friction condition, 0.02 of friction coefficient and 0.129% of wear rate can be obtained. In summary, the composite prepared in this paper can meet the application requirements of polymer bearing bush and have broad application prospects in the field of automobile and ship.
