Abstract

Studies have been carried out to assess the effectiveness of fire retardants on the flammability of an epoxy composition – graphene and an organophosphorus compound DOPO-THPO. The concentrations of the added flame retardants were 2 and 4 % (mass). Flammability characteristics were determined using the method according to GOST 28157 (UL 94) with vertical and horizontal samples. It was found that the introduction of fire retardants reduces the flammability of the epoxy composition, but the introduction of even 4 % was insufficient to ensure self-extinguishing of the epoxy composition during vertical testing.
