A Novel Structure for Carbon Nanotube Reinforced Alumina Composites with Improved Mechanical Properties

摘要

We report the mechanical properties of multi-walled carbon nanotube (MWCNT) /alumina composites made with a pristine MWCNT and an acid-treated version that have nanoscale defects on their surfaces from an acid treatment. Mechanical measurements reveal that only 0.9 vol.% acid-treated MWCNT addition results in 27% and 25% simultaneous increases in bending strength and fracture toughness, respectively.
