CARBONACEOUS SOUND VIBRATORY PLATE AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2010/071090

A1

Disclosed is a carbonaceous sound vibratory plate having a low density while keeping necessary toughness.  A carbon-containing resin such as a vinyl chloride resin is mixed with carbon nanofibers and spherical PMMA particles, and the resulting mixture is carbonized to cause the PMMA particles to disappear.  In this manner, it becomes possible to produce a porous material (16) which contains powder of the carbon nanofibers (12) dispersed in an amorphous carbon (10) and which has pores (14) formed therein.  When a multi-layered structure is formed by laminating the porous material (16) on a porous material (18) which is produced in the same manner expect that PMMA is not used, the density of the structure is further reduced while keeping the toughness of the structure.
