Effect of dynamic load on the Mass fibre composite component

Abstract

Recently there is an increasing interest in composite materials for its applications in .the field of aerospace, marine, automobile, sports, medicine and in many others. Fibre reinforced plastic composite is basically a combination of fibre with binder material to form a new material, which can replace conventional material in various applications. It is necessary to understand the mechanical characteristics of composite under different conditions such as proportion of fibre volume, mode of adhesion between matrix and reinforcement, environmental condition, and process of manufacturing. The advanced composites were developed mainly for aerospace applications because of combination of lightweight, high stiffness, and high strength properties of these materials. The present thesis deals with the fatigue performance of pultruded Glass Fibre Reinforced Plastic (GFRP). A number of tests were conducted under static and cyclic loading to determine their static and dynamic performances. In this research a set-up was designed and fabricated for determining the fatigue life of GFRP. Various samples of different percentage of fibre content were made and tested under static and dynamic loading. It was observed that the optimum percentage of fibre content for resisting the static and dynamic load is proportional to stress. The present investigations contribute to the better understanding of the mechanical behaviours of the Glass Fibre Reinforced Plastics of different fibre orientation and their relationship to their manufacturing parameters and hence to better design of composite structures.
