Experimental Investigation on Mechanical Behaviour of Jute/ Vinyl Ester Composites Impregnated with Alumina Filler

Abstract

The present paper discovers an impact of alumina filler inclusion on mechanical behavior of chemically treated (alkali treated) bi-directional jute natural-fiber-reinforced vinyl ester composites. In practice, the extremity of moisture resorption and poor dimensional stability are the pivotal hindrances of using natural fibers. Currently, chemical treatments assure fiber modifications that increase their resistance when utilized in composite products. Jute fibers are subjected to chemical modifications to the interfacial linkage with the matrix.

A methodic examination has been compassed to look into jute fiber and alumina filler properties when incorporated into vinyl ester matrix. Composites were prepared by using hand lay-up technique. In this study, an exploration has been done to make pre-treated jute fiber (10, 20 and 30 wt.%) and different alumina filler content (1 and 2 wt.%) with vinyl ester - based composites. The investigation reveals that, due to incorporation of jute as reinforcement and alumina as filler into polymer vinyl ester depicts superior mechanical properties ahead of resins alone.
