Beschreibung
Zusammenfassung:	PURPOSE:To obtain a CFRP useful as a member for space devices requiring no application of a metallic film on the surface, having extremely low moisture absorption and low water vapor release, by laminating carbon fiber substrates, impregnating the laminate with an epoxy resin composition under reduced pressure, and curing the epoxy resin composition while pressurizing the laminate in a hot oil. CONSTITUTION:Carbon fiber substrates are laminated, which is impregnated with an epoxy resin composition, which is cured while pressurizing the laminate at >=30atm. in a hot oil lighter than the epoxy resin composition. The hot oil is heated at 70-150 deg., and has
