Provided is a composite material comprising a material containing an inorganic filler and a molded article, wherein the material containing an inorganic filler is prepared by adding the inorganic filler to a polyimide film, a polyimide varnish which comprises a polyamic acid solution, a polyimide precursor film which is produced by drying a polyamic acid solution, and in which an imidization reaction is not completed yet, and which has a self-support property, a polybenzimidazole film, a varnish which comprises a polybenzimidazole solution, a polyazomethine film, a mixed film which comprises a polyimide resin and a polybenzimidazole resin, a mixed varnish which comprises a polyamic acid solution and a polybenzimidazole solution, a mixed film which comprises a polyimide precursor and a polyazomethine, a polybenzoxazole film or the like, and the molded article comprises any one component selected from expandable graphite, an organic fiber and an inorganic fiber. The composite material can be used suitably as a sealing material that can be used as an alternative for an asbestos-made sealing material, or as a heat-release sheet having excellent heat conductivity. |
