摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermally conductive sheet showing excellent thermal conductivity and flexibility. SOLUTION: A method for manufacturing a thermally conductive sheet having a carbon fiber content of 5 to 50% by volume comprises a process of making a carbon fiber sheet having substantially no matrix resin by arranging carbon fiber bundles composed of carbon fibers having a thermal conductivity of 50 to 1,500 W/mK in one direction and bonding the bundles by heat sealing fibers so that they do not separate, a process of obtaining a carbon fiber sheet or a laminate material by laminating two or more sheets in such a manner that the orientation angle of each carbon fiber bundle is in the range from +45 to -45 degrees with respect to a specific direction and a process of cutting the formed material obtained by impregnating the single carbon fiber sheet or the laminate of the carbon fiber sheets with the matrix and curing it in the direction vertical to the specific direction.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a carbon fiber, by which the pitch-based carbon fiber having a high strength even in a high elastic modulus region having elastic moduli exceeding 600 GPa can industrially simply be produced.
SOLUTION: In this method for producing the pitch-based carbon fiber, comprising melt-spinning an optically anisotropic mesophase pitch and then subjecting the obtained fiber to an infusibilizing treatment and a carbonization or graphitization treatment, the pitch is passed through flow-contracting portions approximately linearly disposed in the inlet portion of an introduction hole, expanded in the introduction hole, contracted, and then passed through an extrusion hole to spin the pitch. Thereby, the strength of the pitch-based carbon fiber can be improved by the easily industrially applicable technique without needing a special pitch and without needing a special treatment on the production of the fiber.
