Abstract Efficient improvement of the toughness of epoxy resin has been a bottleneck for growing their appropriateness for advanced application. In this study, thermoplastic polyamide and copolymer composites of thermosetting epoxy resins (DGEBA) were developed via the solution casting method. Polyamide acted as a part of the copolymer as well as a curing agent. Silica nanorods (SiO2 nanorods) were dispersed into the mixture to achieve blends of epoxy/polyamide reinforced silica nanocomposite with various weight ratio viz. 0 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, 9 wt% and 11 wt%. The as-prepared epoxy/polyamide reinforced S iO2 nanocomposites were examined by scanning surface micrograph (SEM), Fourier-transform infrared (FTIR), X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques. The obtained results show that the modified epoxy/polyamides have better toughness than that of pristine epoxy/polyamide polymers. FTIR confirmed the interaction among S iO2 nanorods with epoxy/polyamide. The SEM analysis showed well dispersion of S iO2 nanorods in the epoxy/polyamide blend coating, which demonstrated that this method could effectively avoid agglomeration of the inorganic nanoparticles. In conclusion, this study provides an effective approach to harvest epoxy/polyamide/SiO2 nanocomposite from diverse methods and minerals materials.

essential semi polymeric material, which performs a key role in composite materials [2] . Epoxy resins also created various reinforcing phases and processing techniques [3] . Petroleum-based epoxy blends are well recognized for good behaviors of material such as high stiffness, tensile strength, and good electrical properties [4] . Epoxy resin are broadly utilizing in different fields of constructions, commodity, aerospace industries [5] and automotiv
