Preparation and Mechanics Properties of the EP/TiO₂ Nanocomposites

Abstract:

The EP/TiO₂ nanocomposites were prepared by using epoxy resin as matrix, nanoTiO₂ as the modifier, polyamide as curing agent. The surface morphology of nanoTiO₂ was observed,the average particle diameter of nanoTiO₂ 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 49.2% and 45.2% comparing with their of the pure epoxy resin. At the same nanograins content, with the transfiguration speed increasing, their compressive strength added.
