EXPERIMENTAL INVESTIGATION OF NATURAL FIBRE REINFORCED POLYMER COMPOSITE

Fiber-reinforced polymer composites have a high specific strength and modulus,It have dominated a variety of applications for a long time. Natural or synthetic fibers can be used as reinforcement in reinforced plastics. Only glass, carbon, and other synthetic fibers, according to previous research, have been used in plastics with fiber reinforcement. Despite having a high specific strength and a high cost of production, glass and other synthetic fiber-reinforced plastics have very limited applications. In this regard, a study has been conducted to make use of coir, a natural fiber that can be found in abundance in India. Natural fibers are not only lightweight and durable, but they are also relatively inexpensive. A new set of natural fiber-based polymer composites using epoxy resin as a reinforcement and coconut coir is the subject of this study’s development and characterization. The mechanical properties of the newly developed composites are what set them apart. The effect of fiber length on the mechanical behavior of these epoxy-based polymer composites is the subject of experiments. Coir composites are created and their mechanical properties are evaluated in this work. Filtering electron micrographs acquired from cracked surfaces were utilized for a subjective assessment of the interfacial properties of coir/epoxy. Based on these findings, coir may have potential as a reinforcing material for a variety of structural and non-structural applications. The effects of fiber content, fiber orientation, loading pattern, and fiber treatment on the mechanical behavior of coconut coir-based polymer composites could be investigated further in this work
