Prepreg and fiber reinforced composites |
| abstract |
An epoxy resin cured product that achieves both high heat resistance, elastic modulus, and low colorability is obtained, and when used as a matrix resin for fiber-reinforced composite materials, it does not produce white precipitates on the surface of the molded product and has an excellent appearance. An epoxy resin composition is provided. An epoxy resin composition containing an epoxy resin as component [A] and an imidazole compound as component [B] and satisfying the following conditions (a) to (d). (A): 10 to 40 parts by mass of [A1] isocyanuric acid type epoxy resin as component [A] in 100 parts by mass of all epoxy resins. (B): 40 to 90 parts by mass of [A2] bisphenol type epoxy resin as component [A] in 100 parts by mass of all epoxy resins. (C): The average epoxy equivalent of [A2] is 220 to 500 g / eq. (D): The content of the component [B] is such that the ratio of the number of imidazoles to the number of epoxy groups in all epoxy resins is 0.01 to 0.06. |
