With the rapid development of polyethylene terephthalate (PET) and Polyethylene naphthalate (PEN) and their wide use in industry, there is a substantial volume of plastics added to waste streams every year. Both PET and PEN are not biodegradable and hence causing serious environmental issues. On the other hand, both PET and PEN have very high ductility and low modulus. Conventional fiber reinforced polymer (FRP) such as glass FRP, carbon FRP, and aramid FRP possess high modulus but low ductility. Developing hybrid PET-FRP and/or PEN-FRP presents significant improvement for structural applications such as retrofitting concrete columns using wrapped FRP. The goal of the proposed research is to determine the mechanical characteristics of hybrid PET-FRP and/or PEN-FRP. |
