In this work, the physical and mechanical properties of nano composites are investigate. The nano composites consist of matrix was polyester resin and 3% volume fractions of glass fibers as reinforcement with (0.5%, 1%, 1.5%, 2 %( volume fractions of carbon nanotube as filler. Samples of nano composite materials in this research have been prepared by hand – layup. The results showed that the sample (UP+3% GF) has higher water absorption than sample net polyester. As can be noted from the results that the sample (UP+3% GF+2% CNTs) has higher value water absorption than other samples. Also can be observed from the results that the sample (UP +3%GF+0.5 CNTs) has high values of hardness (shore D), flexural strength, impact strength and fracture toughness from other (1%, 1.5%, 2%) volume fraction carbon nano tube.

This work was carried out to investigate effect of glass fiber (GF) and carbon fiber (CF) on kaolin-clay firebrick properties. GF and CF are considered inorganic fibers with application of high temperatures. Kaolin clay is mixed with short GF and CF separately by different percentages (0, 0.5, 1, 1.5 and 2) wt%. Kaolin-GF and kaolin-CF mixtures were compacted by using the semi-dry pressing method. The compacted specimens were fired at different temperatures (1100, 1200 and 1300)°C. Properties which include bulk density, apparent porosity, water absorption, thermal conductivity and fracture strength were obtained from the firebrick specimens. The results show that the addition of GF has beneficial in lowering of firing temperature, and consequently accelerating the densification via enhanced grain boundary diffusivity. Increasing GF content in the firebrick mixture enhances the fracture strength due to increase amount of glassy and mullite phases. Incorporation of CF has inversely affected than GF on the firebrick properties. As the percentage of CF increased the density of firebrick decreased, and the porosity and water absorption increased.

In the present study, composites were prepared by Hand lay-up molding The composites constituents were epoxy resin as a matrix, 6% volume fractions of Glass Fibers (G.F) as reinforcement and 3%, 6% volume fractions of preparation industrial powder (calcium carbonate CaCO3, potassium carbonate K2CO3 or sodium carbonate Na2CO3) as filler. The erosion wear behavior and coating by natural wastes (Rice Husk Ash) with epoxy resin after erosion were studied. The results showed that the non – reinforced epoxy have lower resistance erosion than industrial based Material composites and the specimen (Epoxy+6%glass fiber+6% CaCO3) has higher resistance erosion than composites reinforced with sodium carbonate and potassium carbonate at 25cm, angle 30°, grin size of sand 850µm, temperature 25Ċ, 200 gm salt content in 3liter of water and 15 hour. Coating specimen with mixed epoxy resin -RHA with particles size in the range (1.4-4.2) µm improves erosion wear resistance characteristics of the coated specimen, coating thickness was (16 ± 1) μm and after erosion in (15 hours) the thickness was (10) μm .Application of the work protection of pipes from erosion, these pipes include the sewage water , drainage pipe laboratory (hot water, chemicals and mineral oil) , pipeline transportation of petroleum products and pipeline transportation of gas products

The composite material was prepared by reinforcing the epoxy with E-glass fiber. The creep and flextural test were measured in this work for one and two layer of E-glass fiber with volume fraction rate of (10%, 20%, 30%, and 40%) in orientation of (0-90o) immersed in epoxy (DGEBA) resin with total thickness of 4mm. The tests were done at different temperature levels from (25 to 55)Co for creep test. The results had revaluated showing that the creeping properties of this composite materials will be improved with increasing the volume fraction layer of fiber at different temperature levels with constant stress. Creeping increases when the temperature increases and decreases with increasing of the number of layers and volume fraction of fiber. The creep constant increases with increasing the temperature up to 45Co then the creep constant down. The creeping energy of epoxy E-glass (epoxy composite) increases with increasing the volume fraction rate of E-glass fiber.

In this work a composite materials is prepared containing matrix of polymer (unsaturated polyester) reinforced with different reinforcing materials (glass fiber + plate fiber) in different values of volume fraction %. All samples for to mechanical tests were prepared by hand layup process. The mechanical tests can be classified into: bending, tensile strength, tensile strength at break, elongation at break and hardness. The study of mechanical test shows that the mechanical properties increase with the increase in volume fraction.
