摘　　要：本研究将复合材料单层板的刚度和强度性能表达成湿热参数的函数,基于经典层合板理论编写了MATLAB计算程序,研究了拉弯载荷比、混杂比、铺层顺序、铺层角度、温度和湿度对湿热环境下单向铺设玻/碳纤维混杂复合材料(G/CFHC)层合板拉弯组合强度的影响和规律。结果表明:湿热环境下,拉弯组合载荷下的单向铺设G/CFHC层合板拉伸载荷方向的强度随拉弯载荷比的增大而增大,弯曲载荷方向的强度随拉弯载荷比的增大而减小;混杂比和铺层顺序对单向铺设G/CFHC层合板的拉弯组合强度的影响较大;单向铺设G/CFHC层合板的拉弯组合强度随铺层角度的增加而减小;单向铺设G/CFHC层合板的拉弯组合强度随着温度的升高而降低,湿态环境会导致强度降低。The stiffness and strength parameters of composite laminas were expressed as functions of moisture and temperature in this article.Based on the classical laminated plate theory,a MATLAB calculation program was compiled,and the influence of tension bending load ratio,hybrid ratio,ply sequence,ply angle,temperature and humidity on the combined tension and bending strength of unidirectional G/CFHC laminates in the hygrothermal environment was studied.The results showed that in the hygrothermal environment,the strength in the tensile load direction of unidirectional laid G/CFHC laminated plates under combined tension and bending load increased with the increase of tension bending load ratio,while the strength in the bending load direction decreased with the increase of tension bending load ratio.The hybrid ratio and stacking sequence had a significant impact on the combined tension and bending strength of unidirectional G/CFHC laminated plates.The combined tension and bending strength of unidirectional G/CFHC decreased with the increase of ply angle.The combined tension and bending strength of unidirectional G/CFHC laminates decreased with the increase of temperature,and the wet environment could lead to a decrease in strength.
