Abstract

Nanocomposites of recycled nylon 11 and titanium based nanofillers were manufactured and their thermal and mechanical behavior analyzed. The nanofillers used vary in dimensions, being classified as 0-dimension (nanoparticles) and 1-dimension (nanofibers). The results show that dispersion of the fillers was the key variable governing the thermal and mechanical properties of the composites. The best performance was obtained for composites loaded with 1% and 5% of TiO2 nanoparticles. For these composites, a 4 fold increase in the Young's modulus was obtained, although the deformation at rupture showed a decrease of almost 50%. The flow curve characteristics at the region of necking stabilization were correlated to a strain-hardening coefficient. It was postulated that the value of this strain hardening coefficient could be used as a measure of neck instability.
