Advances on the Manufacturing Process of Nanocomposites with MWNT and Nanopowders

Abstract:

Epoxy-based nanocomposites with multi-wall carbon nanotubes (MWNT) and nanopowders were fabricated and subjected to monotonic uniaxial testing. Three procedures used to fabricate these nanocomposites are presented, as the dispersion of the MWNTs and nanopowders in the epoxy matrix is a significant challenge. Optical microscopy is used to observe the degree of mixing of the nanofillers in the resin. The inclusion of MWNT and nanopowders don't affect significantly the static properties, but lead to a slight increase of the strength and stiffness of the nanocomposite relative to the neat epoxy.
