Vibration Analysis on Luffa Fiber Reinforced Polyester composites

Abstract

The objective of this process is to investigate the free vibration characteristics of luffa fiber reinforced polyester composites. It also includes the experimental investigation on density and hardness of luffa fiber polyester reinforced composites. The simple laminated plate is fabricated using compression molding machines under the pressure 17MPa.The composite specimen were subjected to modal analysis to obtain natural frequencies and damping values. Damping values obtained are increasing according to the increase in weight percentage. The damping values obtained are higher and ever seen in natural fiber
