Abstract:
(EN) Provided is a resin composition which satisfactorily infiltrates into reinforcing fibers, has rapid-curing properties, and gives cured formed objects having high heat resistance and which is suitable for use as a matrix resin for fiber-reinforced composite materials excellent in terms of the efficiency of short-time production. The resin composition for fiber-reinforced composite materials is a two-fluid curing type resin composition which is configured of a main ingredient comprising an epoxy resin (A) and an acrylate compound (B) having four or more acryloyl groups in the molecule and a hardener comprising an amine compound (C) represented by general formula (1), wherein the mass ratio of the main ingredient to the hardener is in the range of from 90:10 to 65:35. The resin composition is characterized in that the main ingredient has a viscosity at 25°C, as measured with an E-type viscometer, of 20,000 mPa∙s or lower and the hardener has a viscosity at 25°C, as measured with an E-type viscometer, of 800 mPa∙s or lower. X-(CH2NH2)n (1) (In formula (1), X represents a C1-16 n-valent organic group and n is 2 or 3.)
(FR) L'invention fournit une composition de résine qui présente une aptitude à l'imprégnation satisfaisante dans des fibres de renforcement, tout en possédant des propriétés de durcissement rapide, qui présente une résistance à la chaleur élevée d'un produit moulé obtenu lors de son durcissement, et qui se révèle adaptée en tant que résine de matrice pour un matériau composite renforcé par des fibres d'une excellente productivité sur une courte durée. Plus précisément, l'invention concerne une composition de résine durcissable en deux composants qui est configurée au moyen d'un produit principal contenant une résine époxy (A) et un composé acrylate (B) doté de quatre groupes acryloyle ou plus dans chaque molécule, et d'un agent de durcissement contenant contenant un composé amine (C) représenté par la formule générale (1), et dans laquelle le rapport massique du produit principal et l'agent de durcissement est compris dans une plage de 90:10 à 65:35. Ainsi, l'invention concerne une composition de résine pour matériau composite renforcé par des fibres qui est caractéristique en ce que la viscosité à 25°C dudit produit principal mesurée par un viscosimètre de type E, est inférieure ou égale à 20000mPa・s, et la viscosité à 25°C dudit agent de durcissement mesurée par un viscosimètre de type E, est inférieure ou égale à 800mPa・s. X-(CHNH (1) (Dans la formule, X représente un groupe organique de 1 à 16 atomes de carbone et de valence n, et n représente 2 ou 3.)
(JA) 良好な強化繊維への含浸性を示した上で速硬化性も有し、かつ硬化時に得られる成形物の耐熱性が高く、短時間での生産性に優れる繊維強化複合材料のマトリクス樹脂として好適な樹脂組成物を提供すること。 エポキシ樹脂(A)と一分子中にアクリロイル基を四つ以上有するアクリレート化合物(B)を含む主剤と、下記一般式(1)で表されるアミン化合物(C)を含む硬化剤で構成され、主剤と硬化剤の質量比が90:10~65:35の範囲である二液硬化型の樹脂組成物であって、前記主剤のE型粘度計により測定した25℃における粘度が20000mPa・s以下であり、前記硬化剤のE型粘度計により測定した25℃における粘度が800mPa・s以下であることを特徴とする繊維強化複合材料用樹脂組成物。 X-(CHNH (1) (式中、Xは炭素数1~16のn価の有機基を表し、nは2又は3を表す。)
