Abstract

Abstract: The thermal stability of polymer matrix composite could effectively improve by incorporation of highly thermally conductive ceramic materials into polymers. In present work, hybrid PTFE/Nomex fabric/phenolic composite specimens were prepared with zirconium diboride (ZrB2 ) particles for the improvement its high-temperature tribological performances. The thermal stability of hybrid PTFE/Nomex fabric/phenolic composite was investigated by TGA. The result showed that the thermal stability was improved because of addition of ZrB2 particles. In addition, it was found that 9 wt% ZrB2 reinforced hybrid PTFE/Nomex fabric/phenolic composite exhibited optimal tribological performances compared to unfilled fabric composite under all test conditions. Graphical abstract: Highlights: ZrB2 incorporated into hybrid PTFE/Nomex fabric composite to improve it high-temperature tribological properties. The tribological performance was significantly improved under all test conditions. To investigate the worn surface and counterpart pin morphology SEM.
