Fatigue response of hybrid magnesium/APC-2 nanocomposite laminates at elevated temperature

摘要

AS-4/PEEK APC-2 nanocomposite laminates and Mg/APC-2 hybrid nanocomposite laminates were fabricated. The mechanical properties and fatigue response of laminates were obtained due to tensile and cyclic tests at room and elevated temperatures. The surface treatment of chemical etching on Mg sheets resulted in strong bonding with APC-2 laminates. The nanoparticles SiO2 of optimal weight were uniformly spread on the faces of APC-2. From the tensile test the mechanical properties, such as ultimate strength and stiffness, of cross-ply APC-2 nanocomposite laminates were found higher than those of quasi-isotropic nanocomposite laminates. The ultimate strength of hybrid nanocomposite laminates was predicted satisfactorily well with experimental data by using the rule of mixtures.
