Abstract

The mechanical properties of the carbon fiber/Epoxy composite were studied after the addition of nanoparticles for space applications. Three different nano-particles (Al₂O₃, MWCNT, and RGO) were dispersed in the epoxy matrix. Each sample was subjected to ICT electron beam radiation at a constant dose of 100 kGy. The mechanical properties of nanocomposites were tested by a universal tensile testing machine and were correlated to the variation of their constituents’ molecular structure obtained by the Fourier Transformation Infrared (FTIR) spectroscopy. The results revealed an enhancement in the mechanical properties of epoxy matrix after the addition of nanoparticles and preservation of the mechanical properties even after irradiation.
