Title (EN) FIBER-REINFORCED RESIN, PROCESS FOR PRODUCING SAME, AND MOLDED ARTICLE

Abstract:
(EN) The present invention improves the reinforcing effect of reinforcing fibers (A) by using resin particles (B) and a matrix resin (C) in combination with the reinforcing fibers (A) to prepare a resin composition. The reinforcing fibers (A) comprise carbon fibers. The resin particles (B) comprise a semicrystalline thermoplastic resin and have an average particle diameter of 3-40 µm. When heated at a rate of 10 ºC/min in an analysis by differential scanning calorimetry (DSC), the resin particles (B) have an exothermic peak in the temperature range between the glass transition temperature of the semicrystalline thermoplastic resin and the melting point thereof. The semicrystalline thermoplastic resin may be a polyamide resin having a melting point of 150ºC or higher (in particular, a polyamide resin having an alicyclic structure and having a glass transition temperature of 100ºC or higher or a polyamide resin having a γ-form crystal structure or having a degree of crystallization of 50% or less). The matrix resin (C) may be a thermosetting resin.
(FR) La présente invention améliore l'effet de renforcement de fibres de renforcement (A) grâce à des particules de résine (B) et une résine matrice (C) en combinaison avec les fibres de renforcement (A) pour préparer une composition de résine. Les fibres de renforcement (A) comprennent des fibres de carbone. Les particules de résine (B) comprennent une résine thermoplastique semi-cristalline et ont un diamètre moyen de particule de 3 à 40 µm. Lorsqu'elles sont chauffées à une cadence de 10 °C/min dans une analyse par calorimétrie différentielle à balayage (DSC), les particules de résine (B) ont un pic exothermique dans la plage de température comprise entre la température de transition vitreuse de la résine thermoplastique semi-cristalline et le point de fusion de cette dernière. La résine thermoplastique semi-cristalline peut être une résine de polyamide ayant un point de fusion de 150 °C ou plus (en particulier, une résine de polyamide ayant une structure alicyclique et ayant une température de transition vitreuse de 100 °C ou plus ou une résine de polyamide ayant une structure de cristaux de forme γ ou ayant un degré de cristallisation de 50 % ou moins). La résine matrice (C) peut être une résine thermodurcissable.
(JA) 強化繊維(A)と樹脂粒子(B)とマトリックス樹脂(C)とを組み合わせて樹脂組成物を調製し、強化繊維による補強効果を向上する。前記強化繊維(A)は炭素繊維を含む。前記樹脂粒子(B)は、半結晶性熱可塑性樹脂を含み、示差走査熱量測定(DSC)によって10℃/分の速度で昇温したとき、前記半結晶性熱可塑性樹脂のガラス転移温度と融点との間の温度範囲に発熱ピークを有し、かつ平均粒径3~40μmを有する。前記半結晶性熱可塑性樹脂は、融点150℃以上のポリアミド樹脂(特に、脂環式構造を有し、かつガラス転移温度が100℃以上のポリアミド樹脂や、γ型結晶構造又は50%以下の結晶化度を有するポリアミド樹脂)であってもよい。前記マトリックス樹脂(C)は熱硬化性樹脂であってもよい。
