Abstract: Hybrid natural composites have enlarged attention due to its light weight, low cost and low density with high strength to weight ratio and biodegradability. The substantial prominence among the structural materials has been concerned by the natural fibers. The fibers were treated with 5% NaoH and 5% Nacl solutions to take away the lignin content and to progress the adhesion property. In this study, the composite is fabricated by a hand layup process with different fiber orientations and also with different volume fractions. The composites are prepared with three different proportions of hemp-ramie fibers the test plates were prepared according to the ASTM standards. Various mechanical tests are conducted and also, Fast Fourier Technique (Dynamic analysis) is done to determine the frequency and damping ratio of the test plates.
