A flame retardant carbon fiber reinforced composite material that does not contain a halogen atom in a matrix resin, does not generate a harmful gas component in a fire, has excellent flame retardancy, and has excellent mechanical properties. I will provide a. A carbon fiber reinforced composite material comprising a phosphorus-containing epoxy resin (A), a non-phosphorus-containing epoxy resin (B), an epoxy resin curing agent (C), and a carbon fiber (D). (B) The phosphorus content in the matrix resin containing (C) as an essential component is 0.4 to 5.0% by weight, and the phosphorus-containing epoxy resin of (A) is a specific phosphorus-containing compound and an epoxy resin. It is set as the flame retardant carbon fiber reinforced composite material characterized by these. [Selection figure] None |
