Abstract

The results of the investigations into the technological formation of new wear-resistant polymer composites based on polytetrafluoroethylene (PTFE) filled with disperse synthetic and natural compounds are presented. The efficiency of using PTFE composites reinforced with carbon fibers depends on many factors, which influence the significant improvement of physicomechanical characteristics. The results of this research allow stating that interfacial and surface phenomena of the polymer-solid interface and composition play a decisive role in PTFE composites properties. Fillers hinder the relative movement of the PTFE molecules past one another and, in this way, reduce creep or deformation of the parts, reducing the wear rate of parts used in dynamic applications as well as the coefficient of thermal expansion. The necessary structural parameters of such polymer composites are provided by regimes of process equipment.

摘要

介绍了对基于填充分散合成和天然化合物的聚四氟乙烯（PTFE）的新型耐磨聚合物复合材料进行工艺成型研究的结果。使用碳纤维增强的PTFE复合材料的效率取决于许多因素，这些因素会影响物理机械性能的显著改善。这项研究的结果表明，聚合物-固体界面和组合物的界面及表面现象在PTFE复合材料性能中起决定性作用。填料阻碍了PTFE分子彼此之间的相对运动，从而减少了部件的蠕变或变形，降低了动态应用中使用的部件的磨损率以及热膨胀系数。此类聚合物复合材料的必要结构参数由工艺设备的工况提供。
