Commercial ZrO 2 /carbon nanotube (CNT) composite powders were sintered by spark plasma sintering (SPS). The densification behavior during SPS was investigated by analysis of recorded shrinkage plots, and addition of CNTs was found to alter the sintering mechanism. Moreover, the addition of CNTs could also lead to refined grain size, improved fracture toughness as well as reduced Vickers hardness...
A nanoindentation technique was used to investigate mechanical properties (i.e. hardness and modulus) of Nylon 11 (PA11) and its nanocomposites with different clay loading. It has been found that the hardness and modulus of the nanocomposites steadily increase with increasing clay content. With incorporation of 5wt% clay into the PA11 matrix, the hardness and elastic modulus are improved by about...
