摘要： 在考虑湿热应力及湿热环境对复合材料力学性能影响的基础上，按照能量耗散原理及宏观应变能法建立了湿热环境下玻/碳纤维层间混杂复合材料层合梁的阻尼预测模型，并利用MATLAB软件编写了玻/碳纤维混杂复合材料损耗因子的求解程序，研究了湿热环境下温度、湿度、湿热耦合、铺层顺序、铺层厚度及纤维铺设角度对玻/碳纤维混杂复合材料层合梁阻尼性能的影响规律。结果表明：较常温干态环境，湿热条件增大了玻/碳纤维混杂复合材料的损耗因子；当玻璃纤维复合材料单层在外层铺设时，玻/碳纤维混杂复合材料的阻尼性能较好。此外发现，当铺设角度为［±θ］ 、玻璃纤维复合材料单层板位于外层时，玻/碳纤维混杂复合材料层合梁的损耗因子受铺设角度的影响非常显著，当铺设角度为90°时阻尼性能较好。

Abstract： On the basis of considering hydrothermal stresses and the influence of hydrothermal environment on the mechanical properties of composite materials， a 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 method， and the loss factors of glass/carbon fiber hybrid composites were calculated by MATLAB programming. The effects of temperature， humidity， moisture-heat coupling， stacking sequence， ply 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 environment； and 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°.
