Abstract:
(EN) The purpose of the present invention is to provide: an epoxy resin composition which enables the achievement of an epoxy resin cured product that exhibits excellent heat resistance, and which has both good pot life at production process temperatures and excellent curability that enables curing in a short time; and a prepreg and a fiber-reinforced composite material, each of which uses this epoxy resin composition. In order to achieve the above-described purpose, the present invention has the following configurations. Namely, an epoxy resin composition which contains at least the constituent elements [A]-[C] described below, and wherein the functional group equivalent ratio of the amino groups of the constituent element [B] to the epoxy groups of the constituent element [A] is from 0.7 to 1.5 and the blending amount of the constituent element [C] relative to 100 parts by mass of the constituent element [A] is 1-10 parts by mass; and a prepreg and a fiber-reinforced composite material, each of which uses this epoxy resin composition. [A] an epoxy resin [B] an amine curing agent [C] a phenolic compound that is composed of one or more phenolic compounds having a specific structure
(FR) L'objet de la présente invention est de pourvoir à : une composition de résine époxy permettant d'obtenir un produit durci de résine époxy qui présente une excellente résistance à la chaleur, et qui a à la fois une bonne durée de vie en pot aux températures du procédé de production et une excellente aptitude au durcissement dont un durcissement en un court laps de de temps ; et un pré-imprégné et un matériau composite renforcé par fibres, qui utilisent chacun ladite composition de résine époxy. Pour atteindre l'objet précité, la présente invention porte sur la composition de résine époxy suivante. À savoir, une composition de résine époxy qui contient au moins les éléments constitutifs [A]-[C] décrits ci-dessous, et dont le rapport en équivalents des groupes fonctionnels des groupes amino de l'élément constitutif [B] aux groupes époxy de l'élément constitutif [A] est de 0,7 à 1,5 et la quantité d'incorporation de l'élément constitutif [C] pour 100 parties en poids de l'élément constitutif [A] est de 1 à 10 parties en poids. Un pré-imprégné et un matériau composite renforcé par fibres, qui utilisent chacun la composition de résine époxy selon l'invention, sont en outre décrits. [A] résine époxy [B] agent durcisseur amine [C] composé phénolique constitué d'un ou de plusieurs composés phénoliques ayant une structure spécifique
