【 摘 要 】

To meet with the market demands of increasing articles made of different polymeric materials a large number of non-biodegradable polymeric composites have been developed without realizing about the ecological havoc it created. Here we discuss about the Vibration Suppression of Sisal-Epoxy bio-composite containing a layer of magnetostrictive material as actuator. The analytical solutions have been developed on the basis of first order beam theory (TBT) and velocity feedback control to obtain a comparison between different lay-ups and different locations of the magnetostrictive layer. The self-vibration damping property of Sisal Fiber is not considered for calculations.
