Abstract On the basis of considering hydrothermal stresses and the influence of hydrothermal environment on the mechanical properties of composite materialsa damping prediction model of glass/carbon fiber interlayer hybrid composite laminated beams under hydrothermal environment was established according to the principle of energy dissipation and the macroscopic strain energy methodand the loss factors of glass/carbon fiber hybrid composites were calculated by MATLAB programming. The effects of temperaturehumiditymoisture-heat couplingstacking sequenceply thickness and fiber ply angle on the damping properties of glass/carbon fiber hybrid composite laminated beams were studied under hydrothermal environment. The results show that the loss factors of glass/carbon fiber hybrid composites are increased by hydrothermal conditions when compared with normal temperature and dry environmentand the damping properties of glass/carbon fiber hybrid composites become better when the glass fiber composite laminas are laid on the outer layers. it is also found that the loss factors of glass/carbon fiber hybrid composite laminated beams are significantly affected by ply angles when the glass fiber composite laminas are located in the outer layers and the ply angles are ±θ. The damping properties are relatirely good when the ply angle is 90°.
