PURPOSE:To mold the titled molded article having a high porosity, sharp pore diameter distribution and improved mechanical strength, by molding a mixture of short carbon fiber, binder resin, and soluble particulate substance under heating and pressure, eluting the soluble paticulate substance, calcining the resultant substance. CONSTITUTION:A mixed mass of (A) 100pts.wt. short carbon fiber having about 3-30 diameter of fiber and <= about 2mm. length of fiber and (B) 20-100pts.wt. bnder resin (e.g., phenol resin) is crushed. 100pts.wt. prepared crushed material is blended with (C) 20-100pts.wt. soluble particulate substance having a given particle diameter and prticle size distribution, the blend is pressed under heating and molded into the desired shape. The prepared molded article is immersed in (D) a solvent and the soluble particulate substance is dissolved and removed. The resultant substance is dried, calcined at about 800-1,200 deg.C, and carbonized. For example, polystyrene and benzene, starch and water, etc. may be used as a combination of the soluble particulate substance and the solvent. |
