A Novel Method for Preparing Preforms of Porous Alumina and Carbon Nanotubes by CVD

Due to their remarkable mechanical properties carbon nanotubes are proposed ideal as reinforcements in a new generation of composites. In this paper, the technique of producing very porous alumina and then growing carbon nanotubes in the volume is presented. The mixture of porous alumina and carbon...

Zusammenfassung:	Due to their remarkable mechanical properties carbon nanotubes are proposed ideal as reinforcements in a new generation of composites. In this paper, the technique of producing very porous alumina and then growing carbon nanotubes in the volume is presented. The mixture of porous alumina and carbon nanotubes can be used as preforms to manufacture composites by infiltration, which omits the necessity for the step of nanotubes dispersion in the matrix.
