|
Abstract:
以聚四氟乙烯(PTFE)和聚醚醚酮(PEEK)为原材料，制备了PEEK/PTFE复合材料。研究了10% PEEK对PTFE的力学性能、摩擦学性能的影响。结果表明，在力学性能方面，添加10% PEEK的PEEK/PTFE复合材料的抗拉强度比纯PTFE提升了11.51%，抗压强度提升了40.76%，断裂伸长率降低了16.21%。在摩擦学性能方面，磨损率降低了实现了17.65%。通过扫描电镜观察磨损后的表面形貌，揭示了PEEK对PEEK/PTFE复合材料摩擦性能的影响规律，为研发新型PTFE基复合材料提供理论参考。
PEEK/PTFE composites were prepared using polytetrafluoroethylene (PTFE) and polyetheretherketone (PEEK) as raw materials. The effect of 10% peek on the mechanical and tribological properties of PTFE was studied. The results showed that the tensile strength, compressive strength and elongation at break of PEEK/PTFE composites with 10% peek were 11.51%, 40.76% and 16.21% higher than those of pure PTFE. In terms of tribological properties, the wear rate was reduced by 17.65%. The effect of peek on the friction properties of PEEK/PTFE composites was revealed by observing the worn surface morphology with SEM, which provided a theoretical reference for the development of new PTFE matrix composites.
