| titleOfInvention | Epoxy resin compositions, prepregs and fiber reinforced composites |
| abstract | PROBLEM TO BE SOLVED: To provide an epoxy resin composition having an excellent balance of elastic modulus, deformation ability, fracture toughness and heat resistance, a prepreg made of the epoxy resin composition, and a fiber-reinforced composite material obtained by curing the prepreg. To do. SOLUTION: The following components [A], [B], [C], [D] and [E] are all included, and the following conditions (1), (2), (3) and (4) are all satisfied. , Epoxy resin composition. [A]: Trifunctional or higher amine type epoxy resin [B]: Bisphenol F type epoxy resin [C]: Bisphenol A type epoxy resin with an average epoxy equivalent of 1,400 or more [D]: Core shell type rubber particles [E] : The dicyandiamide (1) component [B] consists of two types [B1] and [B2], and the average epoxy equivalent of [B1] and [B2] is 5 <the average epoxy equivalent of [B1] / [B2]. Satisfying average epoxy equivalent <10 (2) Contains 6 to 18 parts by mass of component [D] with respect to 100 parts by mass of total epoxy (3) Dynamic viscosity of the epoxy resin cured product obtained by curing at 135 ° C. for 2 hours. The stored elastic ratio G'in the rubber state in the elastic measurement is 8 <G'<15. (4) The glass transition temperature of the epoxy resin cured product obtained by curing at 135 ° C for 2 hours is 140 ° C or higher [selection diagram] None |
