Abstract: The paper incorporates some micromechanical investigations for the prediction of damping coefficients of two-phase continuous fiber reinforced composite. The effect of the shape of fiber cross-section and fiber volume fraction on the various damping coefficients viz. η11, η22, η33, η12, η13, and η23 is studied through the application of viscoelastic correspondence principle to the model based on Eshelby's method and Mori–Tanaka approach. The damping coefficients expressed as loss factors are predicted using several other micromechanical models like, Unified micromechanics, Haplin–Tsai, Hashin, and Tsai. Loss factors for composite reinforced with cylindrical continuous fiber are also determined by 2D micromechanical FEM/strain energy approach and compared with the predictions made by other methods/theories.
