Abstract

Abstract Polybutylene terephthalate (PBT) composites were prepared with 1.0 phr synthetic :wollastonite nanofibers (SWN), natural wollastonite (NW) and graphene :oxide (GO) to study the effect of different fillers on mechanical, thermal, tribological,and flammability properties. The properties of PBT composites arerelated to the size, structure, and interfacial adhesion of the fillers in PBT matrix. PBT/SWN demonstrated the highest tensile strength and Young's modulus (6% and 9% increment), followed by PBT/NW (1.3% and 7% increment) and PBT/GO (2% decrement and 4% increment). PBT/SWN gave the highest degradation temperature (409�C), followed by PBT/GO (404.7�C). The maximum enhancement in wear resistance (73%) by PBT/SWN and anti-friction performance (26%) by PBT/GO evinced the excellent load-bearing ability of SWN and the great lubricating effect of GO. PBT/NW had the lowest peak heat release rate, smoke, and carbon dioxide production rate. This study shows that :PBT composites have great potential in different automotive applications. :KEYWORDS :flame retardance, friction and wear, mechanical properties, polymer-matrix composites,thermal properties Received: 24 August 2022 Revised: 28 October 2022 Accepted: 15 November 2022 DOI: 10.1002/app.53463 J Appl Polym Sci. 2022;e53463. wileyonlinelibrary.com/journal/app © 2022 Wiley Periodicals LLC. 1 of 17
