Abstract

The effect of carbon fibers (CF) of the Belum brand is explored from the standpoint of influencing the performance parameters and the structure of polymer composite materials (PCM) based on ultra-high molecular weight polyethylene (UHMWPE). It is established that composites having CF content in the amount of wt % exhibit the optimum set of properties. The wear resistance increases by a factor of 3.3, while the deformation and strength characteristics of the material remain at the level of unfilled UHMWPE. It is found that the creep of PCM having composition UHMWPE + 5 wt % Belum is two times less than that of the initial polymer. We also compared the physical and mechanical properties of material developed having unfilled UHMWPE and modified polytetrafluoroethylene (PTFE). It is shown that the creep of UHMWPE is 1.5 times less than the creep of PTFE. The creep in the composite based on UHMWPE is 13 times less than the creep of the composite based on PTFE.

开发基于超高分子量聚乙烯的摩擦工程复合材料

摘要

从影响基于超高分子量聚乙烯（UHMWPE）的聚合物复合材料（PCM）的性能参数和结构的角度探讨了Belum品牌的碳纤维（CF）的作用。已确定具有重量百分比含量的 CF 含量的复合材料表现出一组最佳性能。耐磨性增加了 3.3 倍，而材料的变形和强度特性保持在未填充 UHMWPE 的水平。发现组成为UHMWPE+5wt%Belum的PCM的蠕变比初始聚合物的蠕变小两倍。我们还比较了使用未填充 UHMWPE 和改性聚四氟乙烯 (PTFE) 开发的材料的物理和机械性能。结果表明，UHMWPE的蠕变为1。比聚四氟乙烯的蠕变小5倍。基于 UHMWPE 的复合材料的蠕变比基于 PTFE 的复合材料的蠕变小 13 倍。
