EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL METHOD FOR PRODUCING EPOXY RESIN COMPOSITION FOR FIBER-REINFORCED COMPOSITE MATERIAL PREPREG AND HONEYCOMB PANEL

摘要

An epoxy resin composition for a fiber-reinforced composite material capable of being cured at a low temperature, excellent in flame retardancy and storage stability, and capable of obtaining a cured product excellent in adhesiveness to a honeycomb core, a method for producing an epoxy resin composition for a fiber- Providing prepreg and honeycomb panels. The epoxy resin composition for a fiber-reinforced composite material of the present invention comprises a reaction product obtained by reacting 100 parts by mass of a phosphorus-containing epoxy resin containing phosphorus atoms in a skeleton with 5 parts by mass or more and 20 parts by mass or less of an amino-terminated butadiene-acrylonitrile rubber, Containing epoxy resin, a curing agent, and a curing accelerator, in addition to the phosphorus-containing epoxy resin.
