Cure kinetics and viscosity modelling of a high-performance epoxy resin film

High-performance starch-modified graphene oxide/epoxy nanocomposite coatings: A glimpse at cure kinetics and fracture behavior

Epoxy is a versatile resin used in different fields such as coatings, colors, colorants, and composites. Adding nano-scale fillers/additives to the epoxy has valued epoxy coatings for engineering applications, and opened the time of advanced epoxy-based nanocomposite coatings. In the present work, graphene oxide GO was chemically functionalized with starch, as a natural polymer, and added to th...

Cure Kinetics and Rheology Characterization of Soy-based Epoxy Resin System

A novel soy-based epoxy resin system was synthesized by the process of transesterification and epoxidation of regular soy bean oil, which has the potential to be widely usable in various composite manufacturing processes. Cure kinetics and rheology are two chemical properties commonly required in process modeling. In this work, the cure kinetics and rheology of the soy-based resin system were m...

Viscoelastic Properties of an Epoxy Resin during Cure

The cure dependent relaxation modulus of an epoxy resin was investigated over the entire range of cure extent. Parallel plate rheometry was used to measure the material behavior below the gel point of the epoxy network. Creep testing in three-point bend was used for specimens cured past gelation. All data were converted to the stress relaxation modulus for comparison of the material behavior am...
