Title:
HIGHLY FUNCTIONAL COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/004386
Kind Code:
A1
Abstract:
Disclosed is a novel highly functional composite material which is excellent
in mechanical performance, electrical conductivity and electromagnetic wave
absorption. Also disclosed is a method for producing such a highly functional
composite material. Specifically disclosed is a highly functional composite
material comprising a ceramic polycrystalline body composed of a plurality
of first alumina-magnesia ceramic crystals, and a nanocomposite body (1) having
a structure wherein a plurality of carbon nanotubes (2) and a plurality of crystals
of a second alumina-magnesia ceramic (3) are intertwined with each other. The
nanocomposite body (1) is dispersed in the ceramic polycrystalline body. The
total composition of the highly functional composite material containing the
ceramic polycrystalline body and the nanocomposite body (1) is composed of 0.1-90
mass% of the carbon nanotubes and 99.9-10 mass% of the alumina-magnesia ceramics.
The alumina-magnesia ceramics are composed of 99.8-0.5 mass% of alumina and
0.2-99.5 mass% of magnesia.
