基于ABAQUS的混杂纤维增强复合材料固化变形模拟

FEA on Process Induced Distortion of Hybrid Fiber Composite Based on ABAQUS

针对混杂纤维增强复合材料固化变形问题,以两种纤维增强双马树脂基复合材料为研究对象,建立了一种基于ABAQUS的混杂纤维增强复合材料固化变形预测模型。大尺寸(500 mm×500 mm)平板固化变形实验结果表明,建立的有限元数值模拟计算方法能够较准确的预测混杂纤维增强复合材料固化变形的变形趋势和最大变形量,最大变形量测算误差约为10%~15%。

The characteritsic performances of two different bismaleimide based fiber reinforced composites were tested,and a finite element model for predicting the process induced distortion of hybrid fiber composite was built.The FEA results show that this finite element model can predict the distortion trend and the maximum distortion amount of hybrid fiber reinforced composites accurately.Compared the model output and the experiment result,the error is about 10%-15% considering the maximum distortion amount.
