【 摘 要 】

Glass-Epoxy Composites are having a wide range of applications due to its light weight and low cost. This paper deals with the fabrication of Glass-Epoxy composites having a composition of 70-30% with Aluminium powder as a filler material. The percentage of aluminium is varied by 2%, 4% and 6% by volume. Aluminium due to its high strength to weight ratio finds its application in many areas. The composite plates are fabricated as per ASTM standards and Tensile test and 3-point bending tests are carried out to determine the mechanical properties of the composite. Modal Analysis is done using Fast Fourier Transform and the analytical results are obtained from Nastran. The experimental and Analytical results are compared with each other.
