PURPOSE:To enhance heat resistance of the title composite material by applying liquid resin on woven fabric or nonwoven fabric and alternately laminating it with an expanded graphite sheet. CONSTITUTION:Woven fabric or nonwoven fabric consisting of glass fiber and organic fiber is impregnated with liquid resin obtained by dissolving phenol resin and epoxy resin, etc., in a solvent. Both fabric and an expanded graphite sheet are alternately laminated so that both outer layers are constituted of the expanded graphite sheet, and pressed to form a composite material. Thereby strength and impermeability for liquid are enhanced.
