Effect of Post-mixing Vacuum Degassing time of MWCNT/Epoxy Mixture and MWCNT Content on the Flexural Behaviour of MWCNT Filled Glass/Epoxy Composite

In the current examination, adjustment of epoxy resin has been conducted by multi-walled carbon nanotube (MWCNT) by a consecutive cycle containing stirring, sonication and followed by vacuum degassing (VD). Accentuation has been centred on the impact of I) VD time (4, 12, 18 and 50 hours) of MWCNT/epoxy mixture and ii) MWCNT content in the epoxy resin (0.1 and 0.3 wt. % w.r.t epoxy) on flexural properties of MWCNT installed glass/epoxy-composite (MWCNT- GE) concerning the control glass/epoxy (GE) composites. Greatest flexural quality in the MWCNT (0.1%)- GE composite was acquired with 18 hours VD (27% higher than the control GE), whereas modulus was found to be maximum with 12 hours VD (nearly22% higher than control GE). Incorporation of a higher MWCNT content (0.3wt. %)resulted in a poor flexural performance due to agglomeration as confirmed from scanning electron microscope(SEM).
