湿热环境下单向铺设玻/碳纤维混杂复合材料拉弯组合强度
Combined Tension and Bending Strength of Unidirectional Glass/Carbon Fiber Hybrid Composites in Hygrothermal Environment
摘要
Abstract
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.关键词
