In this work, the influence of ageing on vibration characteristics of jute/polyester composite was investigated by varying the fiber length and weight percent. The ageing of composite was carried out under normal and seawater in room temperature. From the result, it is observed that the composite with the fiber length of 5mm and 25-weight percentage has least moisture absorption and permeability than other types in both normal and seawater due to better fiber-matrix adhesion and closed pack arrangement of fibers. In addition, the above said combination shows better stability and vibration properties are least effected. Further, due to aging, the bonding between fiber and matrix is significantly affected to a larger degree with increase in the fiber content and length, which in turn decreases the natural frequency and damping properties of the composites.
