High performance Mg based hybrid five-layered composite laminates were fabricated by means of sandwiching the AZ31 Mg foils with the Carbon/PEEK prepregs, in which the nanoparticles SiO2 were uniformly spreaded at the interfaces, through hot press. The basic mechanical properties of the cross-ply hybrid laminates were obtained by tensile tests, and they were found in good agreement with the prediction by the rule of mixture. Then, the response due to constant stress amplitude tension-tension (T-T) cyclic loading at elevated temperature up to 106 cycles was investigated.The received S-N curves, when normalized by their corresponding ultimate strength, were found very close to each other. That strongly hints the higher resistance to fatigue of cross-ply hybrid laminates at higher temperature is accomplished.
