Mechanical properties and numerical analysis of FW-hybrid FRP shafts using high strength glass fiber

Abstract

In this study, mechanical properties of FW-hybrid FRP shafts using glass fiber and carbon fiber were investigated. Two kinds of FW-hybrid FRP shafts were fabricated by a filament winding apparatus. One was the HGF/CF hybrid shaft using high strength glass fiber (HME-Glass) and carbon fiber (T700SC-24K), and the other was the EGF/CF hybrid shaft using general-purpose glass fiber (E-glass) and carbon fiber (T700SC-24K). The experimental results revealed that shear strength of HGF/CF hybrid shafts were higher than that of EGF/CF hybrid shafts. The experimental behavior of the EGF/CF hybrid shafts was compared with numerical results. As a result, the numerical results in the linear region of torsional torque and twist angle curves are good agree with experimental results.
