Evaluation and measurement of the damping properties of laminated CFRP composite plates

The main objective of the present investigation was to examine how the damping properties of laminated composite plates vary with changes in the plate dimensions. Also, it was very important for plates with different ply-orientations to see how the dynamic characteristics vary from one plate to another or when the fibre-orientation was changed. The theoretical prediction of the natural frequency, mode shape and specific damping capacity for each mode obtained using the finite element method was to be compared with experimental results.
