Title:
EPOXY RESIN COMPOSITION, PREPREG, AND FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/003690
Kind Code:
A1
Abstract:
Provided is an epoxy resin composition with which an epoxy resin cured product with a high heat resistance and elastic modulus as well as a low colorability can be obtained, said epoxy resin composition not producing white deposits on a surface of a molded good when used as a matrix resin of a fiber-reinforced composite material, and thus having a superior external appearance. The epoxy resin composition includes an epoxy resin as a component [A] and an imidazole compound as a component [B], and satisfies the following conditions (a)-(d). (a): For the component [A], [A1] an isocyanuric acid type epoxy resin is included at 10-40 parts by mass within 100 parts by mass of the total epoxy resin. (b) : For the component [A], [A2] a bisphenol type epoxy resin is included at 40-90 parts by mass within 100 parts by mass of the total epoxy resin. (c): The average epoxy equivalent weight of [A2] is 220-500g/eq. (d): The included amount of the component [B] is an amount such that the ratio of the number of imidazoles to the number of epoxide groups within the total epoxy resin is 0.01-0.06.
