Reaktionsschritte

Polyvinyl chloride resin of 54 mass % and carbon nanofibers of 1.4 mass % having an average grain diameter of 0.1 μm and a length of 5 μm as single-layer molded amorphous carbon source having a porosity of 50% and PMMA as a pore opening member to form pores were mixed together to form a composition and diallyl phthalate monomer as a plasticizer was added to this composition, the composition was then dispersed using a Henschel mixer, kneaded repeatedly a sufficient number of times using a pressure kneader to obtain a kneaded composition, which was then pelletized using a pelletizer to obtain a composition for molding. This pellet was used to perform extrusion molding for a film-like molded product having a thickness of 400 μm through extrusion molding. This film was processed in an air oven heated to 200° C. for five hours to be a carbon precursor. The film was then heated in a nitrogen gas at a temperature rising rate of 20° C./h and left for three hours at 1000° C. The film was naturally cooled and then kept under a vacuum at 1500° C. for three hours, naturally cooled, carbonization completed and a composite carbon vibration plate was thus obtained.
