The paper presents the study on the damping properties of hybrid composites.The damping measurement of composite materials indicates that glass fiber (GF) and carbon fiber (CF) in hybrid composites have reverse contribution to the ultimate mechanial and the damping properties.It shows that a balance between the modulus and the damping factor can be reached by careful selection of the resin matrix and fiber category,fiber volume and hybrid layer design.In addition,the storage modulus and glass transition temperature (T g) of composites have the same influence factor.
