Abstract
Composites are used in practically every area of engineering because to their affordability and biodegradable nature. One of the significant biodegradable polymers that has gained attention internationally over the past ten years for the creation of biodegradable composite is polyvinyl alcohol. Polyvinyl alcohol is used as a matrix in the field of material science because it may be used to make green plastic and composite materials. A modest attempt to create a surface-treated hemp fibre reinforced PVA-based composite has been made in the present work. Maleic anhydride and alkaline treatments were used to alter the surface. After surface treatment, manufacturing of a reinforced polyvinyl alcohol-based cross-linked composite was carried out, and three different weight percentages of hemp (5%, 7%, and 9%) maleic anhydride were used for the experiment. Fabricated samples are firstly examined based on physical tests which consisted of the water absorption tests. Microstructural tests included the Scanning electron microscope (SEM), mechanical
tests comprised of the tensile test and hardness test. Finally, the thermal tests were also done which involved the thermo-gravimetric analysis (TGA) and Dynamic mechanical analysis (DMA). The treated hemp fibre reinforced PVA based composite with maleic anhydride (MA) 7% weight content is confirmed to be the best of all compositions under this scrutiny which was authenticated by the thermal test and mechanical tests.
