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
