Abstract

For utilizing the outstanding energy absorbing capacity of highly elastic carbon nanotube (CNT), bulk multiwalled CNT (MWCNT) structure containing 15 wt% alumina (Al2O3) was fabricated using spark plasma sintering at 1600 degrees C for 10 min under 50 MPa. The compacted mass was similar to 85% dense having morphologically stable MWCNTs. Microindentation studies up to 9.81 N indicated outstanding elastic recovery of the bulk structure leaving only a diffused indentation mark at indenter-specimen interaction zone. Quantitative estimation of elastic response behavior of the fabricated structure using instrumented nanoindentation in 10-300 mN load range indicated promising applicability of Al2O3/MWCNT compact structure as energy absorbing material.
