The thermal properties, mechanical properties, dynamic mechanical thermal analysis, creep and stress relaxation behavior of GO/TLCP/PF hybrid composites were investigated. The results show that the properties of GO/TLCP/PF hybrid composites were obviously improved. The impact strength and the storage modulus of GO/TLCP/PF hybrid composites, GO modified by silane coupling agent KH560, are increased by 25.6% and 28.1%, respectively. Creep and stress relaxation performance has also been improved.
