<P>PROBLEM TO BE SOLVED: To provide a carbon nanotube solidified body connected with silicon carbide where wearing resistance and anti-oxidation property are enhanced by utilizing the high strength and high Young's modulus of carbon nanotubes and to provide its producing method. <P>SOLUTION: The method comprises a coating step to produce coated carbon nanotubes by mixing a polycarbosilane of 8-80 wt.% with carbon nanotubes of 92-20 wt.%, a cross-linking reaction step to cross-link the surface of a polycarbosilane coating film and a firing step to heat-treat the cross-linked coated carbon nanotubes at 800-1,600°C and in a non-oxidizing atmosphere. The carbon nanotube solidified body connected with silicon carbide consisting of carbon nanotubes C<SB>1</SB>-C<SB>N</SB>of 96-30 wt.% and silicon carbide S<SB>1</SB>-S<SB>(N-1)</SB>of 4-70 wt.% and having a bulk density of 1.3 g/cm<SP>3</SP>or more is obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
