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
