Study on Epoxy Nanocomposites Viscoelastic Properties through Dynamic Shear Rheological Analysis Method

Image
   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract Some extraordinary determinations have been made to investigate the epoxy-based nano-composite properties and the viscoelastic curing kinetics for several different industrial applications, such as aircraft, wind energy, defense, and automotive applications. In this research work, the rheological properties of epoxy-based nano-composites containing altered percentages (0%, 1%, 2%, 4%) of nanoparticles (such as carbon [C] and zeolite) were investigated by utilizing a dynamic shear rheological analyzer. Here, the curing kinetics of commercially available thermosetting epoxy resin (Loctite EA 9394 Aero) was studied in detail. It was found that the addition of nanoparticles, such as CB and zeolite in varying proportions (0%, 1%, 2%, and 4%) significantly improved the viscoelastic properties and the curing kinetics (storage modulus, loss modulus, and tan δ) of the nano-composites, which may be helpful in bet...

Authored by Kurbanbekov ShR                                                                             Abstract The paper presents kinetics of hydrogen sorption of Ti-23.5at%Al-21.5at%Nb alloys in isothermal conditions underthe temperature of 450, 500 and 550 °С. It was determined that maximum quantity of absorbed hydrogen is observed at material of sorbed alloy under the temperature of 550 °С. That presents approximately 0.289mass%. It had been found that hydrogen is released under the temperatures within 700 …790 °С. In addition, it was revealed that maximum release of hydrogen composes 85% of samples saturated...
