Effect of MWCNTs on the Tension–Tension Fatigue Behavior of Woven Angle Ply GFRP Laminates
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.
