    • It is an object of the present invention to provide a fiber reinforced composite material combining good properties such as toughness and impact resistance and to provide an epoxy resin composition to obtain this. This object is achieved by the an epoxy resin composition comprising the following [A], [B], [C], and [D]: [A] a diglycidyl ether-type epoxy resin having a molecular weight of 1,500 or more; [B] an epoxy resin in which an SP value of a structural unit thereof is greater by 1.5 to 6.5 than an SP value of a structural unit of [A]; [C] a diglycidyl ether-type epoxy resin having a molecular weight of 500 to 1,200; and [D] an epoxy resin curing agent, in a ratio that satisfies the following formulas (1) to (4): 0.2≦A/(A+B+C+E)≦0.6;  (1), 0.2≦B/(A+B+C+E)≦0.6;  (2), 0.15≦C/(A+B+C+E)≦0.4; and  (3), 0≦E/(A+B+C+E)≦0.2,  (4) wherein A, B, and C represent weights of [A], [B], and [C], respectively, and E represents a weight of an epoxy resin other than [A], [B], and [C].
    • 本发明的目的是提供一种结合韧性和耐冲击性等良好性能的纤维增强复合材料,并提供一种环氧树脂组合物来获得。 该目的通过包含以下[A],[B],[C]和[D]的环氧树脂组合物来实现:[A]分子量为1,500以上的二缩水甘油醚型环氧树脂; [B]结构单元的SP值比[A]的结构单元的SP值大1.5〜6.5的环氧树脂; [C]分子量为500〜1200的二缩水甘油醚型环氧树脂; 和[D]环氧树脂固化剂,其比例满足下述式(1)〜(4):0.2< lE; A /(A + B + C + E)≦̸ 0.6; (1),0.2≦̸ B /(A + B + C + E)≦̸ 0.6; (2),0.15≦̸ C /(A + B + C + E)≦̸ 0.4; 和(3),0≦̸ E /(A + B + C + E)≦̸ 0.2,(4)其中A,B和C分别表示[A],[B]和[C] E表示除[A],[B]和[C]以外的环氧树脂的重量。
