A Review on Plastic Behavior of Polymer Sheets and Forming Process-Juniper Publishers

Image
Authored by Eun Ho Lee Abstract This paper presents a mini review about plastic behaviour of polymer sheets. The fundamental of plasticity and concept of constitutive modeling are introduced. As an application of the plastic behaviour, studies on forming process of polymer sheets are presents. Finally, the future woks are also discussed in the conclusion section. Keywords: Polymer; Plastic behaviour; Forming; Target temperature; Lightweight; Metal flow Introduction Polymer is one of widely used material due to the great availability and low cost. For mass production, moulding and extrusion technologies have been widely employed for polymer processing in industries [1]. Recently, automotive industries are trying to reduce the weight of the vehicles for improving the fuel efficiency [2]. For the reason, they have an interest in polymer materials, and many researchers have studied mechanical behavior of polymer materials. Fi...

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...
