Abstract

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.
