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.

Abstract

In this research study Hardness (shore D), Water absorption, Flexural, Impact Test, and Fracture Toughness of polymer nano composites.The polymer nano composites based on unsaturated polyester resin reinforced with Kevlar fibers (K.F). The samples are attended by hand lay – up method according to (Rule mixture) for various volume fractions of unsaturated polyester resin, fiber and carbon nanotube. The polyester resin was matrix strengthened with 3% volume fraction from Kevlar fiber and (0.5%, 1%, 1.5%, 2%( volume fractions of carbon nanotube. The water absorption, hardness (shore D), flexural test, impact testand toughness fracture properties were studied. Results showed that the water absorption increase with volume fraction increase of fiber with Carbon Nanotube, the sample (polyester+3%K.F+0.5% CNTs) has lower water absorption than other samples. The hardness (shore D), flexural test, impact testand toughness fracture for the sample (polyester+3%C.F+0.5% CNTs) has higher value for Nano- composites.
