Abstract: The effects of the thermal stability and combustion performance of special epoxy resin (AG-80/JD-919) with added graphene nanoplatelets (GNS) was studied. Firstly, GNS was incorporated into the epoxy resin through solution blending method. And then the thermal stability and flame retardant properties of the flame retardant epoxy resin were tested and analyzed by thermogravimetric analyzer (TGA) and cone calorimeter (CCT). The results showed that when the dosage of GNS was 6 wt%, the char residue of epoxy resin increased by 4.6%, and the peak heat release rate (pHRR) and total heat release (THR) decreased by 40.63% and 15.43%, respectively. Therefore, GNS can improve the thermal stability and flame retardant properties of epoxy resin, which is mainly related to the physical barrier effect of GNS in the thermal decomposition process of epoxy resin matrix.
