Epoxy composites based on resins having high flexibility reinforced with functionalized carbon nanotubes

Abstract

The present paper was aimed at achieving a study on carbon nanotubes-reinforced composites and involved obtaining and characterization of composites based on epoxy compounds modified with hydroxyl groupscontaining compounds (glycols). In order to obtain high flexibility epoxy resins-based composites, carboxylfunctionalized MWCNTs were used as filler at a concentration of 0.5 %. The influence of the weight concentration in CNTs on the mechanical and thermo -mechanical properties of the epoxy compounds was evaluated in comparison to mechanical properties of the DGEBA standard composites reinforced with 0.5 % MWCNT.
