In this research a polymeric composites have been prepared using epoxy resin reinforced with fiber glass and two nano fillers silicon oxide SiO2 particle size around 35 nm and titanium dioxide TiO2 particle size around (100-150 nm). These composites have been prepared in square slices (25x25) cm and 8mm thickness. by saturating fiber glass mattresses in the liquid epoxy resin with nan... https://fitnessgravesyardes.shop/product-category/acoustic-grommet/
