Title:

Document Type and Number:

WIPO Patent Application WO/2004/031289

Kind Code:

A1

Abstract:

An orientated carbon nanotube composite comprising a matrix of heat conductivity lower than that of carbon nanotubes and, incorporated in the matrix, carbon nanotubes orientated in a given direction, wherein at least some of the carbon nanotubes are brought into contact with each other so as to provide continuity from one end to another end, along the orientation direction, of the orientated carbon nanotube composite. This orientated carbon nanotube composite is presented as a material of heat conductivity markedly high as compared with that of copper, aluminum or the like, or a material capable of, when disposed in a rubber material of low heat liberation, markedly increasing the heat conductivity thereof. Also, there are provided a process for producing the orientated carbon nanotube composite, and provided, produced using the orientated carbon nanotube composite, a pneumatic tire, wheel for vehicle, tire wheel assembly and disk brake.
