In aerospace applications research efforts are focusing on the design of advanced composite materials reinforced with ceramic nano-fillers. Such advanced materialscombine weight saving with multifunctional properties, including thermal, mechanical and electromagnetic ones. In the present investigation, the effect of dispersion of bothmulti-wall carbon nanotubes (MWCNTs) and Al2o3 nanoparticles on the mechanical characteristics of epoxy matrix was studied. The results revealed that, themicrohardness, impact energy and flexural strength were improved by dispersion of MWCNTs and Al2o3 nanoparticles. However, the tensile strength wassignificantly reduced by dispersion of the aforementioned nanofillers.Keywords

The mechanical and dynamic behaviors of Epoxy/MWCNTs and Epoxy/Al2O3 Mnanocomposites were investigated in this study. Tensile and impact properties were measured for the two nanocomposites. Free vibration test was applied to measure frequency responses and damping factors. The results showed a reduction in the mechanical properties as well as the damping factors. Frequency response and damping factor was strongly affected by the weight percent of the nanofillers. MWCNTs enhanced the bonding between the Epoxy resin and nanotubes causing reduction in the ability to dissipate energy and improvement in stiffness. The results also demonstrated that, the natural frequency of nanocomposites was increased by increasing the weight percent of nanofillers. The damping factor has the same down trend with the mechanical properties of the nanocomposites.Keywords
