In case that composite structures are designed, dynamic properties such as resonance frequency and loss factor as well as the conventional static properties such as strength and elastic modulus must be evaluated. It has been said that the loss factor measurement is very difficult and various experimental conditions make a great influence on the loss factor. Canti-levered beam method is the most popular measurement method of loss factor. In this study the clamping stress is directly measured in this method, the influence of the clamping stress upon the loss factors in unidirectional CFRP laminae with 0deg. and 90 deg. fiber orientation angles are checked. Moreover the difference of influences in these laminae are discussed by using the 2-dimensional finite element analyses.
