Preparation and Mechanical Properties of Carbon Nanotubes Reinforced Barium Aluminosilicate-silicon Nitride Composites
Dense multiwail carbon nanotubes (MWNTs) reinforced barium aluminosilicate (BAS)-silicon nitride (Si3N4) composites were fabricated by hot-pressing sintering. The effect of MWNTs on the microstructure, compositional investigations, as well as mechanical characterization of the composites was investigated. The results show that MWNTs were preserved in the composites after sintering and present good adherence to matrix grains. The incorporation of 3% 1-2μm MWNTs effectively improved the fracture toughness of the BAS/Si3N4 composites from 8.02 to 8.6 MPa·m1/2.
