PURPOSE:To obtain the titled bulky sheet having improved chemical resistance, electrical conductivity and strength, by impregnating a sheet consisting of an organic fiber, pulp, and a binder for paper making with a solution of an organic high polymer substance, press molding it, carbonizing it under heating. CONSTITUTION:(A) 70-95pts.wt. organic fiber consisting of regenerated cellulose or pitch fiber and/or polyacrylonitrile fiber is blended with (B) 3-25pts.wt. pulp such as cellulose pulp, etc. and (C) 2-15pts.wt. binder for paper making, consisting of polyvinyl alcohol fiber, etc. and processed into paper to give a sheet, which is impregnated with (D) a solution of an organic high polymer substance such as phenolic resin, etc., dried and precured. The sheet is then press molded, and, if necessary, it is subjected to infusible treatment, and carbonized in an inert atmosphere under heating at >=800 deg.C, under pressure of pressing preferably at 2-50g/cm<2>, to give the desired molded sheet. |
