| Abstract | ||
| The work focuses on the preparation of hybrid polymer matrix composite materials prepared from the unsaturated polyester resin as matrix reinforced by woven glass fiber kind ( E-glass ) and graphite particles as first group of samples and the second group of samples reinforced with woven Kevlar fiber kind (49) instead of glass fiber. This work includes studying the effect of selected volume fractions ( 0% , 5% , 10% , 15% , 20% ) of graphite particles with mixture of different particle Size of ( 25 μm – 106 μm ) on the properties of the prepared composite materials, Number of mechanical tests were done,they include (Tensile, Compression, Impact, Flexural Strength, Shear Stress and Hardness), which done at room temperature Result of the work shows that the values of (Tensile stress, Tensile elastic modulus, Fracture Toughness, Hardness) increase with the increase of graphite particle volume fraction for both groups samples. As well as the values of the (Compression elastic modulus, Flexural strength, Shear stress) increase with the increase of low values of graphite particles volume fraction for both groups of samples. Where as the values of Impact strength of the prepared composite material decreased with the increases of volume fraction of graphite particles for both group samples. As well the result shows that the values (Tensile stress, Tensile elastic modulus, impact strength, Fracture toughness) for hybrid composite materials reinforced by Kevlar fiber are higher than values reinforced by glass fiber instead of Kevlar fiber, While the values of (Compression stress, Flexural Strength, Shear stress, Hardness) for hybrid composite materials reinforced by glass fiber are higher than values reinforced by Kevlar fiber instead of glass fiber. | ||
