The thesis study use of polymer reinforced by fiber as an alternative to reinforcing steel. reinforcing rod are manufactured by using long glass fibers (reinforced material) and unsaturated polyesters (base material) with 1% methyl acetone peroxide by a manual process similar to continuous molding. . Reinforcing rod of the composite material with a diameter of 12.5 mm, which is equivalent to half of inch, which is more common in construction applications after many attempts of using different types of glass fiber. The surface finish of the reinforcing rod of the composite material was two types (smooth and the other rough by sand treatment to increase bond strength between reinforcing material and concrete). The results showed that the tensile strength of the composite material was high and the bending properties were acceptable at the expense of the bending coefficient. Compression strength was within a close range of all concrete samples, this is due to the fact that the concrete itself shows high compressive strength as well as reinforced concrete with coarse sand-coated material rod showing high compression resistance due to increased compression coefficient. The bending resistance of the un-reinforcing concrete is low and the reinforced concrete with the reinforcement rod of the coarse sand graded material shows a significant improvement in bending resistance as a result of increased bonding with the concrete and higher interaction from iron-reinforced concrete at the expense of bending coefficient.
This thesis had been scientific evaluation by Assistance Prof Dr Fahima Mohammed Fahad / University of Mustansiriya / Engineering College/ Department of Materials Engineering and linguistically by Prof Dr. Arkan Khalkhal Hussein / University of Technology/ Mechanical Department. The discussion of the thesis had been performed at the Fadul Attya hall, and the discussion’s committee agreed to award the student master degree.

The thesis study developing properties poly methyl methacrylate PMMA by using different types of natural fibers (Bamboos and swak fibers) as reinforcing phases. The fibers are treatment alkaline with sodium hydroxide to improving bonding between the matrix and fibers. Different weight fractions fibers’ (3, 6, 9) %wt., and different lengths, (2, 6, 12) mm, had been used to in this study. Mechanical properties include: tensile strength, elongation percentage, young modulus, bending modulus, fracture toughness, hardness, and roughness, physical properties include: density, water adsorption percentage, thermal properties, and other characteristic tests such as: FTIR, DSC, SEM, had been performed. The results show that tensile strength, young modulus, bending modulus, fracture toughness, maximum shear stress, hardness, water adsorption, thermal diffusion, and thermal conductivity increase with increasing fibers’ length and weight fraction for both types of natural fibers. On other hand impact resistance, specific heat, and density decrease with increasing fibers’ weight fraction, while elongation values at fracture decrease with increasing fibers’ length.
This thesis had been scientific evaluation by assistance Prof Dr. Mohsen Abed Allah Abed Hussein / Baghdad University / Engineering College/ Mechanical Department and linguistically by Prof Dr. Arkan Khalkhal Hussein / University of Technology/ Mechanical Department. The discussion of the thesis had been performed at the Fadul Attya hall, and the discussion’s committee agreed to award the student master degree.
Research published
On 10/10/2017 The International Scientific Journal of Engineering Research and its Applications in India Published in Issue No. 7, Vol. 10, part II research for lecturer Hind Bassel Ali teaching in the Department of Materials Engineering / University of Technology, the research was titled: Effect of fill density on compressive properties in molten precipitation modeling process The study examined the effect of the filling density of the samples in the molten deposition process. One of the three-dimensional printing techniques was applied to the compressive properties. It is shown that when increasing the fill density which is one of the variables of the molten precipitation modeling process.

Meeting with representatives of the class
On 23/10/2017 Assist Prof. Dr. Ahmed Mohamed Hassan Al-Ghabban-Head of Materials Engineering / Agency and Assist Prof. Dr. Emad Saadi Abdul Karim - Administrative Assistant met with representatives of the class for all stages in the preliminary study, where the discussion of several topics, the most important of which:
1 - Prepare a model for the uniforms of the Department of Materials Engineering with the identity of the department.
2 - Commitment to attend the study and respect the dates of lectures and review the schedule of absences on a regular basis.
3 - Review the website of the department on a continuous basis for the purpose of obtaining the lecture for each teaching, which is published on the site periodically and follow-up changes in them, The Head of the Department also stressed the need to adhere to the instructions for the prevention of the ready lecture and copies, and only to deliver the lecture.
4 - Preserving the public property in the department and abide by the instructions in addition to maintaining the cleanliness of the department, attention and reporting to the presence of strangers within the department.
