摘要: A slurry containing a precursor fiber convertible to carbon fiber and/or a carbon fiber and, based on 100 parts by weight of the fiber, 10 to 300 parts by weight of a thermosetting resin, e.g. phenol resin, is processed into a random web. This web may contain a pitch or an organic granular material. The web is hot-pressed between a pair of belts while curing of the resin is inhibited to prepare a prepreg sheet. This sheet is disposed, leaving a clearance, in a mold having ribs on a molding surface and heated over the melting point of the resin for expansion and complete cure to provide a porous composite sheet equipped with grooves. This porous composite sheet is carbonized or graphitized to produce a porous carbonaceous material for use as a fuel cell electrode material and so on. This porous carbonaceous material has high homogeneity, gas permeability, electrical conductivity, heat conductivity and mechanical strength.

摘要: A surface-roughened film and methods for fabricating same. The film has good transparency/exceptional clarity and high lubricity so that it is useful for a photoengraving material, label, packaging film, magnetic recording film, or clear film. The film has a composition including thermoplastic polyester resin (a) and a thermoplastic resin (b), such as an amorphous nylon, having glass transition temperature preferably 10.degree. C. higher than that of the thermoplastic polyester resin (a) and a critical surface tension more than 0.1 dyne/cm different from that of the thermoplastic polyester resin (a). Resin (b) further has a melt viscosity, at a temperature of 280.degree. C. and shear rate of 10.sup.2 sec.sup.-1, in the range of 500 to 50,000 poise. One or more particulate inert inorganic compound may be added and the film may be laminated to layers of other polymers with the film of the foregoing composition on at least one surface thereof. On the film surface, microprotuberances cored with the thermoplastic resin (b) are formed.In addition, there are also provided methods for fabricating the surface-roughened film including drawing the film in at least one direction by a factor of at least one and one-half at a temperature between Tg of (a) and Tg of (b).
