AbstractEpoxy-based composites are one of the most promising lightweight materials, while the obtention of fire safety usually accompanies with the sacrifice of mechanical properties. Herein, efforts were paid to coordinate the mechanical performance and the fire safety of the epoxy-based composite. Nanodiamond (ND) was modified with P species, Cu species, and (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) step by step, to strengthen the mechanical performance and further optimize the fire safety of the ammonium polyphosphate (APP)/epoxy composite simultaneously. The developed composite successfully improved the APP/epoxy composite on tensile properties, glass transition temperature (Tg) and heat release performance in the fire, meanwhile, kept the advantages on storage modulus and other fire safety performances (vertical burning test, limited oxygen index (LOI) and cone calorimeter). After studying the changes to ND and the composite performances that brought about by the every-step modification to ND, the nice improvement on heat release performance was supposed to be mainly contributed to the improved charring effect and the free radical scavenging effect of TND, and the improved tensile properties were due to the formed CueN bond in the curing process that connected Cu species, ND and epoxy matrix together. Model experiments were designed to further verify the reinforcing mechanism.
