Participation in a master defense

Assistant prof. dr. Sarmad Emad Ibrahim at University of Technology/ Materials Engineering Department participated in a master defense of the student Zahir Intisar, the dissertation entitled "Energy dissipation behaviors and mechanical characteristics of hybrid concrete subjected to dynamic loading" on Tuesday, September, 15th, at Almustansyria University/ College  of Engineering. The Committee included:
 
1. Professor Muhammad Muslih Salman as a chair.
2. Assistant Professor Tawfiq Wasmi Muhammad- as a committee member.
3. Assistant Professor Sarmad Emad Ibrahim- as a committee member.
4. Assistant Professor Yasir Khleel Ibrahim- as an advisor and a committee member.
5. Dr. Hamza Mustafa Kamal- as an advisor and a committee member.

Abstract:
In this work, a hybrid concrete composite prepared by adding two fibers types, steel, and polypropylene. Firstly, two groups ofconcrete samples made by incorporating steel and polypropylene fibers individually at different volume fractions ( 0.25, 0.5, 0.75, 1 % ). This work designates the effects of hybrid fibers and its modulus on concrete dissipation energy under various dynamic loadings (ultrasonic pulse velocity UPV, Impact strength), and measured as a hybrid and individual fiber concrete.
New concrete properties results showed that adding fibers to the concrete mixture would cause a significant reduction in the fresh state properties of Fiber-reinforced concrete (FRC). Steel fibers reinforced concrete (SFRC), always shows better results in all the strength types than polypropylene fiber reinforced concrete (PFRC), while for the Hybrid fibers reinforced concrete HFRC group shows an intermediate value between the fore mentioned groups related to conventional concrete.

Abstract

The purpose of this study is to prepare graphene nano sheets from graphite flakes and to improve the properties of the ionomer glass cement by adding different volume fractions of graphene, as the graphene was prepared using the planetary wet ball milling method as a basic method in addition to the use of both ultrasound and centrifugation as assistants. the prepared materials were characterized using various techniques such as (scanning electron microscopy, Raman spectroscopy, XRD) and others.

The results proved the success of the method used to convert graphite into graphene, in addition to improving the properties of the nanocomposite (glass ionomer cement + graphene), specifically at the volume fraction of 0.2% graphene.

Abstract
The aim of the research is to fabricate polystyrene polymeric membranes by electrospinning technique followed by the chemical modification by sulfonation reaction.  Sulfonation reaction was done by sulfuric acid as a sulfonation agent at two concentrations (98% and 20%), so the membranes gain proton conductivity properties as well as ion exchange capacity. The membranes would be able to use as a solid electrolyte in proton exchange membranes fuel cells.
