Abstract
In this study, hybrid composite materials were manufactured using the hand lay-up technique, where epoxy was used as a matrix material and two types of reinforcement were glass fibers and particles of natural material (tamarind seed particles (TS)( and coffee bean particles (CS)). The mechanical and physical properties of these composite materials were studied. Also, these materials were characterized by using Fourier Transform Infrared FTIR, Differential Scanning Calorimetry DSC, and Field Emission scanning electron microscopy FE-SEM. Because of the natural material's high moisture sorption, it was chemically treated with (NaOH).
The results showed that the mechanical properties improved by increasing the weight percentages of TS and CS, when compared with pure epoxy and (epoxy +glass fiber), and the percentage (20 wt%) of both natural particles.
physical propertites improved by increasing the weight percentages of TS and CS (density, thermal conductivity, and acoustic insulation)
DSC characterization revealed an increased glass transition temperature value with increasing both natural particle weight fractions.
From FE-SEM results, it is clear that the fracture pattern became ductile after adding chemically treated natural particles. Furthermore, these treated naturals led to increased surface roughness and interfacial adhesion of hybrid composites, in addition to homogenous dispersion of particles within the matrix.

Abstract
The advanced ceramic ZTA (biolox) is used in artificial joints. ZTA (biolox) was synthesized and modified by using (0.25, 0.5, 0.75, and 1) wt. % of CaF2 and MgO. The sol-gel technique was utilized to make a nanocomposite powder using aluminum, zirconium, strontium, and chromium salts. The characterization, physical, mechanical, and biological properties were studied. The results show that CaF2 improved the mechanical properties of ZTA except for hardness, which decreased with increasing CaF2 concentration from ~16.84 to 14.50 GPa. However, MgO has two effects on ZTA properties depending on its concentration: below 0.75 wt.%, the effect enhances ZTA properties, but above this concentration, the effect reverses and causes a significant reduction in properties.

Abstract
In this study, different laminated composite materials were suggested for modifying the prosthetic socket in order to increase its life and make it more comfortable for its user. Seven laminated composite materials were prepared by using the vacuum molding technique. The matrix material is Lamination80:20 (PMMA) and reinforced by (hemp, Carbon, Glass, Kevlar, and Perlon) fibers with different numbers of layers. The experimental work included mechanical, physical, and miscibility tests. After comparing between laminated composites, hybrid lamination consisting of (4hemp plus 2carbon) is considered to have best mechanical and physical properties such as tensile strength, modulus of elasticity, flexural strength, flexural modulus, max. shear stress, compression strength, impact strength, fracture toughness, and hardness. In addition, it has a lower percent elongation and creep strength than the hybrid laminations made of (4hemp plus 2kevlar) and (4hemp plus 2glass).

Abstract:
Merging membrane technology with the photocatalytic activity of nanomaterials is a promising approach towards minimizing membrane fouling consequences. In this work, nanocomposite membranes were synthesized by non-solvent induced phase inversion process, by immobilizing Tungsten Oxide (WO2.89) nanoparticles (NPs) in polyether sulfone matrix. The results showed that membrane's properties and pollutants' rejection, flux recovery ratio, and flux were improved after NPs addition. It was also found that after exposing the samples to UV light irradiation, the flux recovery ratio was improved for the NPs modified membranes compared to neat membranes. It was found that the flux value at longer time for the NPs modified membranes after irradiation were higher compared to the modified membranes with same NPs loading without irradiation.

Abstract
This thesis lies in two main parts; experimental and analytical work. In the first part, an analytical model was prepared to analyze and calculate the dynamic behavior of the random copolymer polypropylene pipe (PP-R) conveying fluid, using Integrated Transformation Techniques (ITT). In the second part, a semi-active control system was designed using Proportional-Integral-Derivative (PID) controller, by employing the shape memory alloy (SMA) wires, made of nickel titanium alloy (Nitinol), to mitigate the vibration of the pipes caused by the fluid flowing inside them. The results demonstrated that there was a large increase in pipe deflection and a significant decrease in natural frequency with increasing temperature and aspect ratio under different fluid velocities. The results manifested that there is a reduction in the level of vibration (about 75%) was obtained by thermal activation of the shape memory wires which leads to alter the dynamic response of the pipe.
