Abstract

In the present study, nano composites were prepared by Hand lay-up molding. The nano composites component of the unsaturated polyester resin (UP) as a matrix, 3% volume fractions of Carbon Fiber (C.F), Glass Fibers (G.F), Kevlar Fiber (K.F) as reinforcement and (0.5%,1%, 1.5% and 2%) volume fractions of Carbon Nanotubes (CNTs) as filler. The erosion wear behavior of this nano composite at four different impingement angles 30°, 45°, 60° and 90° and four angular silica sand abrasive particle sizes 400, 500 , 600 and 800 μm and density were studied. The results showed that the specimens (UP + 3% (GF, CF, KF) +2% CNTs) have the maximum density when compared with the other volume fractions. The non – reinforced unsaturated polyester have lower erosion resistance than nano composites and the specimen (polyester +3% carbon fiber + 0.5% CNTs) has higher erosion resistance than other nano composites at 15cm, angle 30°, grin size of sand 400µm and 15 hour. Application of this work in protection of aircraft structure, turbine blades and pipes from erosion. The Taguchi experimental design ANOVA shows that the filler content factor has great effect on erosion rate of CNTs filled carbon, glass and Kevlar fibers reinforced unsaturated polyester resin.
