湿热环境下树脂基复合材料层合板强度分析方法

Strength Analysis of Resin Matrix Composite Laminates in Hygrothermal Environment

考虑湿热环境对复合材料的影响,在经典层合板理论的基础上对本构模型进行修正,使用逐渐累积损伤分析方法建立湿热环境下层合板强度预测模型。以T300/BMP316含孔板为研究对象,在ANSYS有限元软件中开展不同湿热环境下的拉伸强度数值仿真预测研究,预测结果与试验结果相比误差在±5%以内,证明了模型的可靠性。

As to the influence of the hygrothermal effect on composite,the constitutive model is modified based on the classical laminated plate theory,and the prediction model of the strength of the laminated plate under hygrothermal environment is established by the progressive damage analysis method.With T300/BMP316 perforated plate as the research object,the numerical simulation and prediction of tensile strength under different hygrothermal environment are carried out in ANSYS.The error between the prediction and experimental results is within±5%,which proves the reliability of the model.
