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.
