Investigation of the Effect of Fiber Orientation on FML Hollow Shaft Subjected to Static Torsion Loading

Sumana BG, Vidya Sagar HN, Krishna M

In this study, the torsional behavior of cylindrical FML hollow shafts was examined by a combined experimental and numerical approach. The FML hollow shafts with glass fibers wound on Al metallic liner at different fiber orientations were prepared using filament winding machine. To examine the effect of fiber orientation, FML hollow shafts of 0/90°, 60/30°, ± 45° and ± 55° fiber orientations were considered. Three different FRP thicknesses of 1, 2 and 3 mm were selected for all fiber orientations to study the torsional buckling and deformation behaviour of FML hollow shafts. Numerical investigation using ANSYS static and linear analysis was performed to validate the end and transition effects of torsional phenomenon. Both the experimental and numerical results showed FML hollow shafts with 0/90° fiber orientation possessed higher torsional strength as compared to FML hollow shafts with 60/30°, ± 45° and ± 55° fiber orientation.
