Abstract: Abstract SiC whisker and Si3N4 whisker-reinforced Si3N4-SiC ((SiCw-Si3N4w)/(Si3N4-SiC)) composite was synthesized by 3D printing for the first time, by the combination of printed-Si-body nitridation and chemical vapor infiltration-SiC methods. The mechanical properties of the composite… read more here.

Abstract: Abstract Herein, a homogeneously distributed and well-orientated ceramic-CNT composite fibre (Si3N4/SiC/CNTs) has been prepared using carbon nanotube fibres (CNTFs) premixed with silicon powder, followed by the reaction-bonded sintering process. The SiC layers around the CNT… read more here.
