2-hydroxyethyl Acrylate Grafted Jute Fiber/ Treated Coir Pith/Vinyl ester Hybrid Composites

The present work demonstrates the fabrication and properties study of Vinyl ester i.e. Bisphenol-A glycidyldimethacrylate (BisGMA) composites hybridized with 2-hydroxyethyl acrylate (HEA-10% w/w) grafted jute fiber and aqueous NaOH (5% w/w) treated coir pith used in various proportions and to characterize thereof. The mechanical and dynamic mechanical properties were measured in dependence of treated & untreated fiber as well as filler content. Composite with HEA grafted jute fiber and coir pith (15 wt%) exhibited maximum improvement in the above mentioned properties. Thermogravimetric analysis indicated the thermal stability of composites due to effective hybridization. The corrosive and water ingress properties of the composites were found to be negligible contributing to longer durability of the panels in moist and corrosive conditions.
