Chemically modified jute fabric reinforced novolac epoxy resin composite
Title of the Research
Chemically modified jute fabric reinforced novolac epoxy resin composite
Introduction
Besides the multiple advantages of environment friendly jute as reinforcing elements in composite, the high moisture absorption and chemical incompatibility with the matrix limits the mechanical, optical and chemical properties of composite[1].A lot of research works have been performed all over the world on the use of cellulosic fibers as a reinforcing material for the preparation of various types of composites. However, lack of good interfacial adhesion, chemical compatibility, and water sensitivity make the use of cellulosic fiber reinforced composites less attractive. Pre-treatments of the jute fibers can modify the fiber surface, such as chemical functionalization stop the moisture absorption process, develop the desirable functionality and increase the surface roughness, which chemically and mechanically interlock jute fiber with matrix [2].
In this research, chemically modified jute fabric would be used in jute-novolac epoxy composite system for the better physical and chemical attachment of reinforcement and matrix phases.
Objectives:
Due to the hydrophilic nature of jute, the interfacial interaction with novolac epoxy resin is weak. The modification with appropriate monomers could provide better interfacial bonding between jute and novolac epoxy resin which leads to improve mechanical and chemical properties of final composite compare to the unmodified fiber reinforced composite.
Methodology:
Jute fabric collected from the local market will be scoured by sodium carbonate and nonionic detergent and then bleached with hydrogen peroxide.
The bleached jute fabric will be treated with NaIO4 to form oxy jute and then grafted with PEG1500. The impregnation of the fabrics with aqueous formulations containing different specific doses of PEG1500 will chemically modify the treated fabric. This treatment would transform the cellulosic chains
