Dense multiwall 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.

Multiwall Carbon

Silicon nitride based composites with 3 wt% different carbon additives (multiwall carbon nanotubes, graphene and carbon black) have been prepared. Optimisation of the manufacturing processes has been conducted to preserve the carbon nanotubes in composites and to avoid damaging during high temperature processing. The results show that carbon additives have a good contact to the surface of silicon nitride grains. It was found that the different carbon additions have significant effect to the electrical, mechanical, tribological and thermophysical properties of silicon nitride based composites in comparison with pure silicon nitride.

Sintering Method

Multiwall carbon nanotubes (MWNT) reinforced iron aluminides (Fe3Al) intermetallic matrix composites have been prepared by a conventional (hot pressing) sintering method. Morphological, structural, compositional and mechanical properties investigations have been performed. Compressive testing shows that the composites still display high yield strength. The first results show that carbon nanotubes have been preserved in composite structure during the sintering process.
