Abstract The fatigue behavior of reinforced composites is complex and the present knowledge of fatigue study still needs extensive investigation of the micromechanical composite behavior. In fiber reinforced composites mechanical properties are highly dependent on their compositions, the matrix type as well as the volume fraction of the reinforcement and their arrangements such as random orientation and distribution, which increase the complexity in the study of fatigue damage behavior. There exist several classes of models to predict the fatigue life or the fatigue degradation of fiber reinforced composites but there exists so far no fatigue model that can be applied to a wide range of fiber reinforced composites. Thus, modifications of fatigue models are always needed in accordance with the micromechanical behavior of different fiber/matrix composites. In this paper the fatigue failure is rectified by using polymer based Kevlar composite material. The design and fabrication involves the design of polymer matrix like as fiber and resin, hardener etc. Kevlar-49 is chosen for as fabricating material to carry out this work. The fabrication set up is made by Vacuum Bag and it is demonstrated satisfactorily. I. Introduction Many of the modern industrial application and technologies require materials with superior properties that cannot be met by conventional monolithic material such as, metal alloys, ceramics and polymers. Considering the principle of the combined action, better properties can be obtained by combination of two or more distinct material. Accordingly, material property combinations have been and yet being extended by the development of the composite, which is a multiphase material that exhibits a propagation of the properties of the forming phases so that a better combination of properties is obtained for making structure. [1-6] Generally Fiber reinforced composite materials are used increasing in many military, aerospace and civil applications due to their excellent mechanical properties like high specific strength, specific stiffness, resistance to corrosion, increased fatigue life among others[7-9]. However, one of main concern in the use of advanced composites is their poor translaminar properties, which become critical under situations like impact loading.
