Abstract

In this study, the Properties of a polyester-based composites, using nanoparticle fillers ((TiO₂) and (SiO₂), were investigated. The mechanical, physical, miscibility and morphology tests were studied Moreover, buckling analysis of nanocomposite plates with cutout was investigated including the effect of design parameters such as cutout shape, size, position, direction, number of cutouts etc. in addition to the plate aspect ratio on the buckling behavior and comparing the experimental and numerical results. The main conclusion was that the presence of cutout could equally well raise the buckling load just as much as lower it. On the other hand, the experimental results were better than the numerical results with percentage (2.3-8.2%). Nanocomposite plates are utilized as underlying parts in aviation, auto and marine designing constructions. Patterns are generally set up as access ports in electrical and mechanical structures or only for decreasing weight.

After the discussion, the committee recorded its notes on the thesis, which were split between explanation and correction, and the student’s defense of her work and the discussion ended. The committee decided to evaluate the thesis and grant the student a master’s degree with a full grade.
