Preparation of Epoxy Nanocomposites and Studying Their Mechanical, Thermal and Morphology Properties

Epoxy resin was used as a matrix , reinforced by nanosilica as a filler in different percentages ( 1, 3, 5, 7 and 10) % to prepare epoxy nanocomposites and a comparison between manual mixing and ultrasonic mixing by studying mechanical properties (tensile strength) , thermal properties ( Limiting Oxygen Index (LOI)) and morphology ( Scanning Electron Microscope (SEM)) to get the best improvement results . The best results were for ultrasonic mixing , at additive content 5% for tensile strength, and noticeable increment in all limiting oxygen index measurements.
