Fiber reinforced polymer composites has been used in a variety of application because of their many advantages such as the relatively low cost of production, easy to fabricate and superior strength compares to neat polymer resins. Reinforcement in the polymer is either synthetic or natural. Synthetic fiber such as glass, carbon etc. has high specific strength but their fields of application are limited due to the higher cost of production. Recently there is an increasing interest in natural fiber based composites due to their many advantages. In this connection, an investigation has been carried out to make better utilization of sisal fiber for making value-added products. The objective of the present research work is to study the physical, mechanical and water absorption behavior of flax fiber reinforced epoxy based hybrid composites. The effect of fiber loading and length on mechanical properties like tensile strength, flexural strength, the hardness of composites is studied. Also, the surface morphology of fractured surfaces after tensile testing is examined using scanning electron microscopy (SEM).
