Abstract
(EN) The present invention addresses the problem of providing an epoxy resin composition that has a low viscosity and excellent impregnation properties; that is stable due to the capability of suppressing an increase in viscosity even at an injection temperature; that can be sufficiently cured in a short time; that, in a demolding step after molding, enables smooth demolding as a result of a resin being sufficiently cured and thus imparting high heat resistance; and that is capable of providing a fiber-reinforced composite material having excellent mechanical properties when moist-heated. Provided is an epoxy resin composition containing: a component [A] and a component [B] indicated below as epoxy resins; and components [C] and [D] indicated below as curing agents, wherein the component [B] is contained in an amount of 10-50 parts by mass with respect to 100 parts by mass of the total epoxy resin component, the curing agents are liquid at 23°C, and H/E, which is the ratio of the total number of epoxy groups (E) contained in the epoxy resins to the total number of active hydrogen atoms (H) in amine compounds contained in the curing agents, is 1.0-1.4. [A] epoxy resin having one or more glycidyl amino groups [B] dicyclopentadiene-type epoxy resin [C] liquid aromatic diamine [D] crystalline aromatic diamine
(FR) La présente invention aborde le problème de la fourniture d'une composition de résine époxy qui présente une faible viscosité et d'excellentes propriétés d'imprégnation ; qui est stable en raison de sa capacité à éviter une augmentation de sa viscosité même à une température d'injection ; qui peut être suffisamment durcie en peu de temps ; qui, lors d'une étape de démoulage après moulage, permet un bon démoulage en conséquence du fait que la résine est suffisamment durcie et confère ainsi une grande résistance à la chaleur ; et qui est capable de fournir un matériau composite renforcé par des fibres présentant d'excellentes propriétés mécaniques après chauffage humide. L'invention concerne une composition de résine époxy contenant : un composant [A] et un composant [B], comme indiqué ci-dessous, en tant que résines époxy ; et des composants [C] et [D], comme indiqué ci-dessous, en tant qu'agents de durcissement, le composant [B] étant présent à raison de 10 à 50 parties en masse pour 100 parties en masse de l'ensemble du composant formé des résines époxy, les agents de durcissement étant liquides à 23 °C, et le rapport H/E, qui est le rapport entre le nombre total de groupes époxy (E) présents dans les résines époxy et le nombre total d'atomes d'hydrogène actifs (H) présents dans les composés aminés contenus dans les agents de durcissement, variant de 1,0 à 1,4. [A] résine époxy comportant un ou plusieurs groupes amine glycidylique [B] résine époxy de type dicyclopentadiène [C] diamine aromatique liquide [D] diamine aromatique cristalline
