Interleaf-containing, fiber-reinforced epoxy resin prepreg

摘要

Disclosed is an interleaf-containing, fiber-reinforced epoxy resin prepreg, which comprises a fiber-reinforced epoxy resin matrix and an interleaf composed of a polyimide film subjected to a corona discharge treatment and/or a matting treatment. This prepreg is suitable for the production of a composite material which is excellent in mechanical strength characteristics such as interlaminar shear strength and flexural breaking strength and having a high toughness.
