Keywords： MWNT

1wt％ multiwalled carbon nanotube (MWNTs) reinforced alumina composites was sintered to full density by spark plasma sintering.And pure alumina and graphite/alumina composites were also prepared by the same way for comparison.Indentation and single edge V-notched beam (SEVNB) toughness were measured respectively.The experimental results show that MWNTs could not improve toughness of alumina too much as that once expected.And SEVNB toughness was more valid than indentation toughness.
