Fabrication and characterization of vapor grown carbon nanofiber reinforced polyester Conference Paper uri icon


  • In the present investigation, a high intensity ultrasonic liquid processor was used to obtain a homogeneous mixture of polyester resin and vapor grown carbon nanofiber. The CNFs were infused into the polyester through sonic cavitations and then mixed with catalyst using a high speed mechanical agitator. To investigate dispersion effect on mechanical properties of CNF/polyester, sonication dispersion were performed at 20minutes, 40minutes, 60minutes and compared with mechanical mixing method. Experimental results show that sonication time has no effect on mechanical properties of neat polyester, but significantly improve dispersion of CNF. Experimental results also show that, at the same processing conditions, 0.2% CNF/polyester provides maximum enhancement in strength. Higher than 0.2%, strength of nanocomposites decreased with increasing CNF content. However, TGA results show that thermal stability of composite is insensitive to the CNF content.
