Abstract
Fatigue characteristics of multiwalled carbon nanotubes (MWCNTs) toughened glass fiber reinforced plastic (GFRP) composites made of woven angle ply (45°/−45°) fabric is presented. Fatigue experiments were conducted under tension–tension fatigue loading for stress ratios 0.1 and 0.3, and at three different stress intensities. The dispersion of 0.5 wt.% of MWCNTs in the modified GFRP resulted in better fatigue lifecycle compared with the GFRP modified with 1.0 wt.% of MWCNTs. In addition, MWCNTs dispersion also affected other fatigue properties, such as fatigue stiffness, cyclic creep, and dissipated energy. Analytical models were employed to demonstrate a substantial amount of reliability in accurately predicting the fatigue lifecycle of MWCNTs modified GFRP. Furthermore, a statistical methodology has been utilized to ascertain the design fatigue lifecycle at different levels of reliability.
