Preparation and Mechanics Properties of the EP/SiO2 Nanocomposites


Article Preview

The EP/SiO2 nanocomposites were prepared by using epoxy resin as matrix, nanoSiO2 as the modifier, polyamide as curing agent. The surface morphology of nanoSiO2 was observed,the average particle diameter of nanoSiO2 is 20nm. Their mechanics properties were studied and the experiment results were analyzed. The results indicated that the compressive stress-strain curves of the nanocomposites had obvious three phases characters, i.e., linear elastic phase, plastic yield flat phase and compact phase. Along with the nanograins content of the nanocomposites increasing, the compressive elastic modulus and compressive strength of the nanocomposites augmented. When the nanograins content is 5% and the transfiguration speed is 10mm/min, the compressive elastic modulus and compressive strength of the nanocomposites respectively improved 22.7% and 35.2% comparing with their of the pure epoxy resin. At the same nanograins content, with the transfiguration speed increasing, their compressive strength added.
