چکیده:

Epoxy resin materials have extensive applications, such as adhesive, medical devices, optical component due to their excellent moisture and chemical resistance compared to many materials, however, during the service or storage of the epoxy resin the environmental factors such as temperature, atmosphere, water, stress, etc can cause the deterioration of its properties, which greatly limits its application. Therefore, it is necessary to study the aging mechanism of epoxy resin.In this study was examined wet ageing on mechanical properties of two component epoxy composites containing different percent of Fumed sillica and aminosilan. Accelerated ageing was performed in natural sea water at 60 °C with different times.Accelerating aging experiments based on response surface method can greatly decrease the number of tests and save money. Some quadratic polynomial fits for the mechanical property were derived from accelerating aging test. The multiple correlation coefficient (R2) of the regression models was about 0.939 confirming the excellent accuracy of developed models
