Abstract: We choose the specific dynamic elastic modulus as an index to judge the dynamic behavior of material. In this article, we conducted the experiment to study the specific dynamic elastic modulus of the faceplate and baseplate of composite Guqin with different plies and compared with wooden Guqin. From the results, we can get the specific plies which are in agreement with wooden Guqin in dynamic behavior. It demonstrated the feasibility of using composite materials to make Guqin, and provided a basis of studying the sound characteristics of composite materials.

Key words: composite material, specific dynamic elastic modulus, Guqin
