Damping Test on Flax and Sisal Hybrid Composites Reinforced with Epoxy Resin

Abstract

The aim of this study is to evaluate frequency, material damping factor, magnitude and phase angle of the composite plate of hybrid sisal and flax reinforced with epoxy resin composites. The hybrid sisalflax laminations are prepared by hand lay-up technique. Sisal and flax fiber as reinforced materials and commercially available epoxy resin as a matrix material. A cantilevered rectangular symmetric plate of hybrid sisal-flax fabric reinforced epoxy composite having dimensions 300x300x5 mm. Damping factor can be varied by taking three different combinations of sisal fiber flax fiber and epoxy resin.
