Abstract:

An epoxy resin prepreg system composed of glycidyl amine epoxy resins modified by dimer acid and other polyfunctional epoxy resins with different viscosities was developed. The hot-melt film method was used to obtain epoxy resin prepregs reinforced by carbon fiber and high-temperature-resistant epoxy composites reinforced by carbon fiber. The application period of the resin could last longer than 60 days. The thermal stability temperature of the solidified product was higher than 300 ℃, and its long-term use temperature was higher than 160 ℃. The composite material exhibited good heat resistance. The heat resistance temperature could reach above 160 ℃, which could meet the heat resistance requirements of high-performance epoxy composites reinforced by carbon fiber.

Key words: carbon fiber, epoxy resin, composite material, high temperature resistance
