چکیده:

In the past decade, spates of research activities have been reported for improving mechanical properties of epoxy composites. Nanoparticles can significantly alter the mechanical properties of the polymer close to the particle surface due to changes in polymer chain mobility. As the matter of fact, silica has played an important role in reinforcement components due to nanoscale effects.In this study, the mechanical properties of epoxy resin based on bisphenol F (DGEBF) with amine curing agent, in the presence of silica filler in comparison of different nanoscale concentrations were determined. The mechanical properties of epoxy nanocomposites were measured via tensile test that were performed on dog-bone specimens (ASTM D3039 with crosshead speed of 1mm/min). SEM pictures were shown the agglomeration event in higher percentage of nanofiller. On the basis of obtained results, the strength of epoxy composite depends on the nanofiller amount because of agglomeration events
