Evaluation of Mechanical and Interfacial Properties of Sisal/Jute/Glass Hybrid Fiber Reinforced Polymer Composites

Natural fiber reinforced composite materials have offered extensive range of properties, such as biodegradability and environmental friendliness. In this experimental study, the partially eco-friendly hybrid sisal/jute/glass hybrid fiber reinforced polymer composites, with varying reinforcements (number of layers) were prepared by using compression moulding process. These composites were characterized by different techniques, for interfacial shear strength, tensile strength, flexural strength, impact strength and water absorption tests. Microscopic examinations were carried out to analyze the interfacial relationship between the fiber and the matrix, fiber dispersion into the matrix and structure of the fractured surfaces, by using the scanning electron microscopy analysis. The results indicated that the hybridization of both sisal and jute fiber with glass fiber, can improve the properties, as compared to single fiber reinforcement of either sisal or jute fiber with glass fiber. Fairly good adhesion and physical properties of these composites indicated their suitability for applications in construction, automobile and aviation industries.
