Abstract:
(EN) Provided is a curable resin composition suitable for use as a matrix resin for a fiber-reinforced composite material having excellent fatigue resistance, the curable resin composition having, low viscosity, minimal increase in viscosity even in a prolonged impregnation step, and good impregnation into reinforcing fibers, and high toughness being obtained in a molded article obtained by curing the curable resin composition. A curable resin composition for a tow prepreg having (A) an epoxy resin, (B) core-shell-type rubber particles, (C) dicyandiamide or a derivative thereof, and (D) a solid aromatic urea compound or a solid imidazole compound as essential components thereof, at least 25% by mass of the epoxy resin (A) being a bisphenol-F-type epoxy resin having a weight per epoxy equivalent of 180 g/eq, the blended amount of the core-shell-type rubber particles (B) being 2-20% by mass with respect to the total amount of components (A) through (D), and the viscosity of the curable resin composition for a tow prepreg at 25°C being in the range of 3 to 45 Pa∙s.
(FR) L'invention concerne une composition de résine durcissable adaptée à l'utilisation en tant que résine de matrice pour un matériau composite renforcé par des fibres ayant une excellente résistance à la fatigue, la composition de résine durcissable ayant une faible viscosité, une augmentation minimale de la viscosité même dans une étape d'imprégnation prolongée, et une bonne imprégnation dans des fibres de renfort, et une ténacité élevée étant obtenue dans un article moulé obtenu par durcissement de la composition de résine durcissable. La présente invention concerne une composition de résine durcissable pour un faisceau de fibres pré-imprégné incluant (A) une résine époxy, (B) des particules de caoutchouc de type noyau-enveloppe, (C) du dicyanadiamide ou un dérivé de celui-ci, et (D) un composé d'urée aromatique solide ou un composé d'imidazole solide en tant que composants essentiels de celui-ci, au moins 25 % en masse de la résine époxy (A) étant constitués d'une résine époxy de type bisphénol-F ayant une masse par équivalent époxy de 180 g/éq. la quantité mélangée des particules de caoutchouc de type cœur-enveloppe (B) étant de 2 à 20 % en masse par rapport à la quantité totale des composants (A) à (D), et la viscosité de la composition de résine durcissable pour un faisceau de fibres pré-imprégné à 25 °C étant dans la plage allant de 3 à 45 Pa∙s.
(JA) 低粘度かつ長時間の含浸工程においても粘度増加が小さく、強化繊維への良好な含浸性を有し、硬化して得られる成形物の靱性が高く、耐疲労性に優れた繊維強化複合材料のマトリクス樹脂として好適に使用される硬化性樹脂組成物を提供する。 エポキシ樹脂(A)、コアシェル型ゴム粒子(B)、ジシアンジアミドまたはその誘導体(C)、固形の芳香族ウレア化合物または固形のイミダゾール化合物(D)を必須成分とし、前記エポキシ樹脂(A)の25質量%以上がエポキシ当量180g/eq以下のビスフェノールF型エポキシ樹脂であって、コアシェル型ゴム粒子(B)の配合量が(A)~(D)成分の合計に対し2~20質量%であり、25℃における粘度が3~45Pa・sの範囲であるトゥプリプレグ用硬化性樹脂組成物。
