Abstract: In this paper, an anisotropic design is introduced to the laminated damped thin plates.Experimental study on the temperature and frequency characteristics of the internal friction and stiffness of several groups of anisotropic damped structures with alternately laminated damping layers or centralized damping core layers was carried out.It will lay the foundation for anisotropic laminated damped structure theory and its light and high damping design.The experimental results show that in the experimental ranges of temperature(0～70℃)and frequency(1～200Hz), the temperature characteristics of both the structural stiffness and internal friction of alternately laminated structures are better than those of the centralized damping core layers structures.However the influence of the frequency on both the structural stiffness and internal friction is not certain.It is related to the concrete structural parameters and the total layer numbers.
