EFFECT OF THE NATURE OF CARBON NANOTUBES ON THE STRUCTURE AND STRENGTH OF CERAMIC COMPOSITES

A composite material based on -Al2O3 and two types of carbon nanotubes obtained from a methane-hydrogen mixture and propane-butane mixture was synthesized. The results of vacuum sintering and a comparative analysis of the structure of the material obtained as a function of the type of nanotubes and their content 3 – 24 vol.% are presented. A composite material with equal crystallite structure and uniform distribution of nanotubes in the matrix, demonstrating an increase in strength in bending to 400 MPa, is obtained.
