In the present work, Epoxy Polymer (EP) matrix (LY 556) has been reinforced with glass fiber (GF) and composites were prepared by hand layout technique with different fractions of fibers (0%, 10%, 20%, 30% and 40%). Randomly oriented and mat type oriented fiber orientations have been considered in the present study. Tensile tests were conducted for all the composite samples. It has been observed that the composite having weight percentage of 30% is showing optimum value of tensile stress for both randomly oriented as well as mat type composite. It was also observed that the mat type composite has more tensile strength compared with randomly oriented. The morphology of optimum glass fiber reinforced fiber composites (GFRFC) was studied by using field emission scanning electron microscope (SEM) to verify the interaction created by hardener (HY 951) between EP and GF. Further, free vibration analysis of mat type oriented composite rectangular plates was done and natural frequency results were obtained and validated with experimental data.
