More Information
Summary:A composite material with a homogeneous distribution of carbon nanotubes, the material is being made of aluminium oxide, corundum or zirconium dioxide or silicon nitride or silicon carbide or aluminium with a volume representation of 90 to 99.5 %, and carbon nanotubes with a volume representation of 0.5 to 10 %. The composite material is showing a high compactness of at least 99 % of theoretical density, with the homogeneous distribution of carbon nanotubes preserved along with ensuring a fine grained microstructure of the alumina matrix with an average size of particles less than 1 μm. L'invention concerne une matière composite ayant une distribution homogène de nanotubes de carbone, la matière étant faite d'oxyde d'aluminium, de corindon ou de dioxyde de zirconium ou de nitrure de silicium ou de carbure de silicium ou d'aluminium ayant une représentation en volume de 90 à 99,5 %, et des nanotubes de carbone ayant une représentation en volume de 0,5 à 10 %. La matière composite présente une compacité élevée d'au moins 99 % de masse volumique théorique, avec la distribution homogène de nanotubes de carbone conservée avec l'assurance d'une microstructure en grains fins de la matrice d'alumine avec une dimension moyenne de particules inférieure à 1 µm.
