On 13/11/ 2017 Master thesis of the student Hwazen Salam  Fadelwhich titled,

“Preparation and characterization bio polymer composite materials for denture applications”,

 has been discussed and the members of discussion’s committee are listed below

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.
