Abstract

The multi-walled carbon nanotube (MWNT) was not consolidated without additives by the spark plasma system (SPS). The phenol resin of 33 wt% was added to promote the consolidation. The MWNTs were aligned perpendicular to pressing direction of SPS in the consolidated compact. Bulk density and Young's modulus were more than 1.7 g/cm³ and 10 GPa for the MWNT consolidated at 120MPa at 1200°C and 1400°C. The fracture behavior on bending test was a kind of quasiplastic deformation and was based on pull out of the MWNTs.
