Processing of carbon nanotube reinforced silicon nitride composites by spark plasma sintering

Effect of Carbon Nanotubes on the Shear Strength and Electrical Resistivity of a Lead-Free Solder

“…[13][14][15] In view of this, in recent years several investigators have introduced CNTs as reinforcements in polymer, metal, and ceramic matrices in an attempt to overcome the performance limits of conventional materials. [16][17][18][19] In our earlier study on SnAgCu/CNT bulk composite solders, 5,6 the experimental results revealed better thermal performance in terms of lower coefficient of thermal expansion (CTE) values and also improved mechanical performance in terms of higher tensile strength and higher creep resistance. In order for such composite solders to serve as electrical interconnects, it is also important to ensure that the electrical properties of these solders are not compromised at the expense of enhanced mechanical and thermal properties.…”

The sintering and grain growth behaviour of ceramic–carbon nanotube nanocomposites

“…Adding CNTs to polymer matrices can significantly increase their mechanical strength [9][10][11], elastic modulus [10,12], impact toughness [12], electrical [9,[13][14][15] and thermal conductivities [15]. Improved mechanical [16][17][18][19], electrical [19][20][21] and thermal properties [22,23] have also been reported for ceramic/CNT nanocomposites produced by rapid processing using Spark Plasma Sintering (SPS). However, the role of CNTs in the sintering of ceramics is not all that clear in the literature, possibly because of differences in the materials used, and particularly because of inconsistencies in dispersion and mixing of the CNTs.…”

The production of advanced fine-grained alumina by carbon nanotube addition

“…However, alumina-CNT composites are previously reported to have lower hardness as compared to monolithic alumina [10,[20][21][22][23][24][25][26] due to various reasons. Jiang et al reported lower hardness and toughness for alumina + 10 vol.% CNT composite due to the degradation of CNTs during sintering [26].…”
