In this article, we investigated the interfacial, thermal and ablative properties of two nanofillers‐filled carbon/phenolic (CF/PR) composites. In particular, graphene oxide (GO) and graphitic carbon nitride (g‐C 3 N 4 ) were used to produce lowly loaded (0.1 wt%) composites. The ablative properties of the composites were researched through an oxygen–acetylene flame torch test and were characterized through analysis of the post‐burning morphology, ablation depth and width. GO‐ and g‐C 3 N 4 ‐filled composites showed 62.02 and 22.36% improvement in ablation resistance compared with the pristine, respectively, even with different mechanisms. The proposed mechanism of GO‐filled composite is that GO may significantly contribute to increasing the graphitization of the fiber surface and further improving the thermal resistance to high‐temperature ablation. However, thicker fiber diameter and charred layer of ablative zone in g‐C 3 N 4 ‐filled composite can dissipate the flammable gases and improve the anti‐oxidation. POLYM.
