Preparation and Mechanics Properties of the EP/ZnO Nanocomposites

Abstract:

The EP/ZnO nanocomposites were prepared by using epoxy resin as matrix, nanoZnO as the modifier, polyamide as curing agent. The surface morphology of nanoZnO was observed,the average particle diameter of nanoZnO 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 36.4% and 48.9% comparing with their of the pure epoxy resin. At the same nanograins content, with the transfiguration speed increasing, their compressive strength added.
