Preparation and characterization of carbon nanotube reinforced silicon nitride composites

Carbon Nanofibers Reinforced Ceramic Matrix Composites

“…They found that CNTs were preserved in the final structures. Problems with degradation of CNT, observed in other instances (Balázsi et al, 2003;Balázsi et al, 2004) were not observed in this newer work. The CNTs were located mainly in the inter-granular places and they were well attached to the silicon nitride grains as well as to each other.…”

“…In the study of Balázsi (Balázsi et al, 2004) the compositions of the starting powder mixtures of the investigated materials were: 90 wt. % Si 3 N 4 , 4 wt.…”

Carbon Nanotube Reinforced Ceramic Matrix Composites- A Review

“…This method produces a ceramic matrix composite (CMC) in which the nanotubes are highly aligned [ Fig.2]. Balazsi et al have devised a novel processing method to make a composite material consisting of a highly durable Si-B-N-C ceramic matrix made from substituted vinylborazine precursors modified by carbonaceous structures on the surface [8]. Depending on the content of Ni dopand of the starting polymer, a catalyzed growth of multiwalled carbon nanotubes (CNTs) of the bamboo-type or of carbon layers is observed [ Fig.3 (a&b)].…”

Preparation and Mechanical Properties of Carbon Nanotubes Reinforced Al2O3/TiC composites

“…However, the low fracture toughness still cannot match the command of many practical fields, which greatly limits its applications [1][2][3] . Carbon nanotubes (denoted by CNTs) have attracted great attention as potential strengthening and toughening materials in industrial applications due to their particular structure, low density, high strength and toughness and excellent corrosion resistance [4][5][6][7] . In this work, carbon nanotubes reinforced Al 2 O 3 /TiC composites (denoted by Al 2 O 3 /TiC/CNTs) were prepared by mechanical milling and hot pressed sintering.…”
