Mechanical properties of short, natural fiber Hildegardia populifolia-reinforced styrenated polyester composites

Short, natural fibers belonging to the species Hildegardia populifolia were reinforced in styrenated polyester matrix. The mechanical properties of these polymer composites such as tensile modulus, compression strength at first deformation, flexural modulus, and izod impact strength were determined. The effect of alkaline treatment of the natural fiber on the mechanical properties of the composites has been reported. The fractured surfaces of these composites were investigated by scanning electron microscopic technique (SEM) to investigate the interfacial bonding between matrix and the reinforcement. The present work has been carried out in order to make partially biodegradable and eco-friendly composites.
