| Abstract | ||
| The recent emergence of nano science and nano technology has added another dimension to the staple of the modern composite technology. Instead of micron diameter fibers and particles, nanoparticles are being incorporated into polymer matrices to form a composite known as polymer nano composites (PNCs). In this study, the composites were prepared from unsaturated polyester and different weight percentages of carbon black (0, 3, 6, 9 and 12 %) nanoparticles using hand lay out. The mechanical properties – such as tensile strength, modulus of elasticity, elongation at break, hardness, bending and impact properties were studied. The results show that the tensile strength, modulus of elasticity, impact strength, fracture toughness, flexural strength and maximum shear stress was achieved at (3wt. %) of carbon black, while elongation at break decreases with an increasing of carbon black weight percentage. The hardness of composite increased with the increasing of carbon black weight percentage | ||
