Abstract[English]
are as defined. A second epoxy resin composition is described that includes [A] at least one epoxy resin, [B] at least two hardeners comprising [B-l] at least one amine compound and [B-2] at least one organic acid hydrazide compound, and [C] at least one accelerator comprising [C-1] at least one organophosphorus compound, where [A], [B] and [C-1] are as defined. A prepreg comprising reinforcing fiber bundles impregnated with the first epoxy resin or the second epoxy resin is also described as well as a fiber-reinforced composite material.[French]
étant tels que définis. L'invention concerne également une seconde composition de résine époxyde qui comprend [A] au moins une résine époxyde, [B] au moins deux durcisseurs comprenant [B-1] au moins un composé amine et [B-2] au moins un composé hydrazide d'acide organique et [C] au moins un accélérateur comprenant [C-1] au moins un composé organophosphoré, [A], [B] et [C-1] étant tels que définis. L'invention concerne également un préimprégné comprenant des faisceaux de fibres de renforcement imprégnés de la première résine époxyde ou de la seconde résine époxyde, ainsi qu'un matériau composite renforcé de fibres.
