In this paper, the measurement and evaluation techniques of vibration-reduction effects based on thin com-posite damping sample are introduced by means of frequency response function (FRF). Experimental study on compo-site samples of four different types of damping material was developed . The FRFs characteristics of the different measuring points on the test samples are compared, and the vibration-reduction effects of the different test samples on four different frequency scopes is computed. It is concluded that the damping measurement and evaluation methods based on FRFs can be used to evaluate performance of the different types of damping materials and structures, and it can conveniently be used to filter damping materials and evaluate the vibration-reduction effects.
