Abstract

The main purpose of this work is to extend the service life of the heat exchanger by protecting the tubes by coating to reduce the fouling phenomenon and increase the corrosion resistance of these tubes, small samples were coated with epoxy and WO3 nanoparticles in different proportions, and these samples were subjected to a number of tests to study their properties before and after coating. Then the heat exchanger experiments of the uncoated tube, the epoxy coated tube and the epoxy and 1 wt% of WO3 nanoparticles were carried out to study the performance of the heat exchanger. The results proved that the tube coated with the nanocomposite coating is the most successful in reducing the expected problems.

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.

Abstract

This work aims to prepare hybrid composite materials to evaluate their behavior under ballistic impact experimentally and numerically. Multilayered armors were designed as ceramic/woven fabric reinforced epoxy/metal or polymer layer. In experimental ballistic tests, a 9 mm Full Metal Jacket FMJ bullet was launched at 307 m/s towards armor 30*30 cm². The Finite Element Method (FEM) is used to simulate the ballistic impact resistance of the armor. The results from simulation and experimental testing were compared with ballistic tests and there was a good agreement of these results.

 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.
