Abstract
Fibre matrix adhesions of sisal fibre with polymer were evaluated in terms of physico-chemical and mechanical properties. Effects of acetylation, acrylation, silanization, alkalization, and permanganate treatment on physical and chemical parameters as well as mechanical parameters such as tensile and impact behavior were investigated. Physical properties like density, moisture absorption, water absorption, void content and chemical properties like percentage of lignin, cellulose, and hemicelluloses were determined. From the findings, it was concluded that treatments such as acetylation, acrylation, and silanization can increase interfacial strength, wetting, and compatibility between fibre and matrix, leading to increase composite tensile strength. Acetylated sisal fibre and its polymer composites showed the highest tensile strength, less water absorption, and the acrylated sisal fibre composites showed the highest impact strength (46900 J/m2).
