•GFRP composite with hybrid particles modified epoxy matrix was fabricated.•Spectrum fatigue tests were conducted on both neat and hybrid GFRP composites.•The spectrum fatigue life of GFRP hybrid composite is enhanced by about 4–5 times.•The constant amplitude fatigue tests conducted and CLD constructed for both composites.•The spectrum fatigue lives were predicted and compared with the experimental observations.
Two types of glass fiber reinforced plastic (GFRP) composites were fabricated viz., GFRP with neat epoxy matrix (GFRP-neat) and GFRP with hybrid modified epoxy matrix (GFRP-hybrid) containing 9 wt.% of rubber microparticles and 10 wt.% of silica nanoparticles. Fatigue tests were conducted on both the composites under WISPERX load sequence. The fatigue life of the GFRP-hybrid composite was about 4–5 times higher than that of GFRP-neat composite. The underlying mechanisms for improved fatigue performance are discussed. A reasonably good correlation was observed between the experimental fatigue life and the fatigue life predicted under spectrum loads.
