基于复合材料细观力学，利用能量耗散原理及宏观应变能法建立了湿热环境下玻/碳纤维混杂复合材料层合梁的阻尼预测模型。利用Matlab软件编写了湿热环境下玻/碳纤维混杂复合材料损耗因子的计算程序，研究了纤维铺设角度、体积分数、铺层顺序以及湿热效应对玻/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：湿热环境导致材料产生湿热应变是影响阻尼特性的主要机理；玻/碳纤维混杂复合材料层合梁的损耗因子均随温度及吸水浓度的增大而增大，且温度的影响远大于吸水浓度的影响；纤维体积分数越高，受湿热影响程度越大；铺层角度对损耗因子影响远高于湿热、混杂方式、纤维体积分数的影响。
Abstract
Based on the mesomechanics of composite materials, the damping prediction model of glass/carbon fiber hybrid composite laminated beams in hygrothermal environment was established by using the principle of energy dissipation and macroscopic strain energy method. The MATLAB calculation program for the loss factor of glass/carbon fiber hybrid composites under hygrothermal environment was written, and the influence of fiber laying angle, volume fraction, laying order and hygrothermal effect on the damping performance of glass/carbon fiber hybrid composite laminated beams was studied. The results showed that: hygrothermal strain is the main mechanism affecting damping characteristics; the loss factors of glass/carbon fiber hybrid composite laminated beams increase with the increasing of temperature and water absorption concentration, and the influence of temperature is much greater than water absorption concentration; the higher the fiber volume fraction, the greater the degree of influence by moisture and heat; the influence of ply angle on the loss factor is much higher than that of moisture and heat, ply mode, and fiber volume fraction.
