This paper describes an analysis of the damping properties of matrix hybrid composite by Lagrange's equation. The damping properties of matrix hybrid composite are calculated by using viscoelastic properties of homogeneous laminated composite. Two kinds of glass fiber reinforced laminated composites are employed. One is chopped strand glass fiber mat reinforced composites, and the other is unidirectional glass fiber reinforced composite. Hybrid composites of both samples consist of conventional and flexible matrix resins. This analysis method is shown to be effective in predicting the loss factor of hybrid composite with flexible matrix resin.
