Bio Caryota Fiber Reinforced Polyester Composites: A Study on Fracture Toughness Mode I

Abstract

The aim of the paper found the fracture toughness of caryota fiber loading with 35wt%, 40wt% and 45wt% having different fiber length of 10mm, 25mm, 50mm, 100mm and 125mm. The fiber have been used in many applications such as automotive, aircraft house hold, sports good etc. The natural fiber posses light weight, low cost and easily available. The stiffness and strength is high for the given weight. In this work caryota fiber reinforced composites were prepared by compression molding machine the chopped fiber varying length varying fiber loading ,the hardener used for the composites 10:1. The SEM analysis has conducted after the fractured specimen to found mode of failure of fractured specimen.
