Abstract
A method for manufacturing the carbon nanotube composite material includes the steps of: providing a substrate, the substrate having a surface; forming a catalyst film in a special predetermined pattern on the surface of the substrate; forming a carbon nanotube array on the catalyst film to obtain the carbon nanotube array having a special predetermined pattern; providing a pair of protective layers, the protective layers being attached on a corresponding portion of ends of CNT array; filling clearances existing among CNTs of the CNT array and between the two protective layers with a matrix material; and removing the protective layers from CNT array.
