Rheological Properties of Al2O3 Nanoparticle Toughened Epoxy Resins

The effect of nanoparticle content on the rheological properties of toughened epoxy resins was studied by measuring the isothermal viscosity-time curves of Al 2 O 3 nanoparticle toughened epoxy resin at different temperatures. The chemorheological properties of toughened epoxy resin systems were analysed using the Dual-Arrhenius equation and a corresponding chemorheological model was established. The model agrees well with the experimental results and provides a theoretical basis for rational development of parameters for Al 2 O 3 nanoparticle toughened epoxy resin based composite molding processes.
