Preparation and properties of a composite SiC with addition of multi-walled carbon nanotubes synthesized in the plasma jet

Ceramic composite reinforced with plaits of carbon nanotubes have been fabricated by the reaction bonded silicon carbide method. Carbon nanotubes (CNTs) are produced using a 35 kW dc plasma torch and C₂H₂ as carbon precursor. Effective methods of CNTs adding and dispersing in the preform volume have been found. The optimal content and operational technological parameters have been determined for ceramic matrix. Physico-mechanical properties of the reinforcing ceramic matrices with nanomaterials have been investigated. (paper)
