Evaluation of mechanical properties of carbon nanotube reinforced composites
Journal Title: Jurnalul Stiintific TURBO - Year 2017, Vol 4, Issue 2
Abstract
The present research was focused on evaluation of multi-wall carbon nanotubes influence on ordinary polymeric composites, starting with integration of the nanotubes, optical microscopic analysis, mechanical testing to determine flexural properties of epoxy nanocomposites and hybrid composites and thermal analysis of hybrid composites. It was observed that changes in the manufacturing process parameters can influence the properties of nanomposites. A reduction in the elasticity of the epoxy matrix was observed after the addition of carbon nanotubes. Also, it was established that even if the nanotubes are functionalized with -COOH group they still present the tendency to form bundles, leading to more rapid failure of the material. The addition of carbon nanotubes between the prepreg plies oriented at 0° leads to a reduction of material’s mechanical properties, while in case of hybrid composites with prepreg plies oriented at 45° an increase of material’s mechanical properties was observed. Regarding the thermal analysis, a slight modification of the hybrid material’s Tg was observed (an increase of 1%).
