Composite materials are replacing traditional materials, because of their superior physical and mechanical properties. The main objective of the present work is to perform stress-strain analysis on Styrene-Ethylene-Butylene-Styrene (SEBS)-epoxy resin composites under reinforcement of fibres and dispersion of CuO, ZnO, MgO, SiO and TiO₂nano metal oxides. Combination of glass fibre with particle reinforcement (GFRPs) applications has increased in recent days. In this study, glass fibre reinforced epoxy composites with different nano metal oxides are developed by compression moulding method and their mechanical properties such as breaking load, elastic limit, plastic range and fracture point are evaluated. The results indicate that the incorporation of nanophase material with glass fibre can improve the properties of composites.
