Enhancement of Impact Strength in Jute Fiber-Reinforced Polypropylene-Spent Coffee Ground Composites
The most abundant biomass material in the world is lignocellulosic biomass. This project aims in the utilization of agro waste/biowaste as fillers in thermoplastics due to the increased needs in overcoming the environmental problems caused by their by-product. Most recent developments in using a biomass material are with jute fibers, palm coir, banana fibers and sisal, etc., as reinforcement. All these natural fibers have excellent physical and mechanical properties and can be utilized more effectively in the development of composite materials for various applications. Various processing techniques and conditions; Compression molding process, Injection molding and extrusion methods are used in composite production.
The aim of the present work is to develop Jute sandwich composite through compression molding for which already compounded spent coffee ground composite of previous work was used as matrix and braided jute fiber were used as reinforcing the material. Mechanical properties like Tensile strength and Impact strength properties were tested and the results 64show there is a decrease in the former properties compared to later. Further chemical testing was also done to determine its resistance and to develop composites for various application.
