The use of natural fibers as reinforcement in polymer composites has become a very popular research area of scientists, researchers and engineers throughout the last decade. Natural fibers have significant properties like low density, high specific strength, low cost, relatively good mechanical properties, eco-friendly and bio-degradability. Due to this, they are used as substitute for the conventional fibers such as glass, aramid and carbon. Recently, it was noticed that kenaf fiber had enormous possibilities for replacing synthetic fiber in composites due to the rising environmental and ecological issues. This consciousness has inspired the efforts for the development of new innovative bio-based composites. In this research work, an experimental investigation has been carried out to make use of kenaf fiber, a natural fiber abundantly available in India. The present work describes the development and characterization of a new set of kenaf fiber reinforced polymer composites. The composites are fabricated using hand lay-up technique and their impact strength is evaluated. The experiments are carried out to study the effect of fiber length and fiber orientation on the impact strength of these composites. The fabricated composites were tested as per ASTM standards to evaluate its impact strength. The experimental results show the notable effect on impact strength of prepared composites. However it is found that the reinforcement of kenaf fiber with preferred orientation can improve the impact strength significantly.
