Investigation on Flexural strength of Polymer nanocomposites modified by MWCNT and Glass fiber

Abstract

The glass-reinforced laminated composite is widely used in place of conventional structural materials. The glass fiber composites demonstrate outstanding strength in the uniaxial direction. The effect of carbon nanotube reinforcement percentage on the flexural strength of glass-reinforced polymer composites is investigated in this article. The flexural strength of the final laminates has been found to improve by reinforcing the Carbon nanotube. The small incorporation of MWCNT improves the flexural strength up to 51.3%. The 1.0 wt.% MWCNT reinforcement into GFRP shows the 51.3% improvement into flexural strength in comparison to GFRP composites. MWCNTs plays a prominent role to enhance the mechanical features of the developed samples. The SEM image is used to examine the nature and mechanics of failure. This study highlights the effect of carbon-based nanomaterial on the glass fiber reinforced epoxy composites.
