Influence of Higher Concentrations of Multiwalled Carbon Nanotubes on the Tensile and Flexural Performance of Glass Fiber Reinforced Polymers

Engineering Reports, Volume 8, Issue 6, June 2026.
The addition of MWCNTs enhanced the tensile and flexural behavior of GFRP composites. Maximum strength and stiffness were obtained at 3 wt% MWCNTs, whereas intermediate contents showed reduced performance due to poor dispersion. The results confirm that uniform nanotube dispersion is essential for achieving reliable mechanical performance in GFRP ...
