Abstract : The weight and fuel savings offered by composite materials make them attractive not only to the military, but also to the civilian aircraft, space, and automobile industries. Recently the interest in using polymer composites in infrastructure applications has grown worldwide and it has been established that polymer based composites reinforced with a small percentages of strong fillers can significantly improve the mechanical, thermal, and barrier properties of the pure polymer matrix. Hence the demand for improving polymer composite performance is required. The main objective of the suggested project is to improve the performance of polymer composite structures through introducing carbon nanotubes to the polymer. Carbon nanotubes (CNT) have attracted particular interest because they are predicted, and indeed observed, to have remarkable mechanical and other physical properties. In this study the mechanical properties of the specimens will be determined through a series of tests such as tensile, compression, fatigue and fracture toughness by manufactured filled and unfilled polymer with carbon nanotubes the filled tested specimens will be manufactured with weighted fractions of nanocomposites ranging from 0.1% to 0.9%. The study showed that by introducing a small quantity of carbon nanotubes enhances the mechanical properties of polymer (SIROPOL 7440-P). Compared to the pure polymer, the tensile strength increased by 24.1% at 0.3% carbon nanotubes, the compressive strength increased by 4.4% at 0.3% carbon nanotubes, the fatigue life cycle increased by 319.5% at 0.1% carbon nanotubes and the fracture stress intensity factor increased by 43.0% at 0.3% carbon nanotubes.
