Natural fibers composites are low-cost fibers with high specific properties, low density and eco-friendly. The development of advanced bio composite materials made is increasing in the world. It will be an alternative way to develop the bio-composites which can be particularly used for daily needs of common people whether it is house hold furniture, house and light weight car components and other equipment. This effort to develop bio-composite materials with improved performance for global applications is an ongoing process. Therefore, it is important to study the water absorption behavior in order to estimate, not only the consequences that the water absorbed may have, but also the durability of natural fibers composites aged under water, to plan a possible surface treatment in order to improve its mechanical properties.
