摘要/Abstract

摘要： 层间剪切强度是评价复合材料层合板层间力学性能的一项重要指标。首先,按照ASTM D 2344开展了复合材料层合板短梁剪切试验,研究了CCF300/5228复合材料层合板层间剪切性能。其次,基于数字图像相关方法得到了不同载荷作用下层间全场位移和应变分布。最后,利用ABAQUS建立了复合材料层合板有限元模型,分析了复合材料层合板层间位移及应变分布,并与数字图像相关计算结果进行了对比。研究表明,数字图像相关方法试验结果与有限元分析结果具有较好的一致性。数字图像相关方法能够实时监测层合板层间应变分布,进而预测层间剪切破坏位置,为复合材料层间剪切性能研究提供有效的全场应变监测手段。

Abstract: Interlaminate shear strength is an important index for evaluation interlaminate mechanical properties of composite laminates. First, the short beam shear tests were carried out according to ASTM D 2344, and the interlaminate shear properties of CCF300/5228 composites were analyzed. Then, the full-field displacements and strains under different loads were obtained using digital image correlation (DIC) method. Finally, a finite element model of the composite laminate was built using ABAQUS, and the corresponding displacements and strains were extracted from the simulation. The simulation results were compared with the experimental results from DIC. The results show that the experimental full-field displacements and strains agree well with the simulation results. The distribution of full-field interlaminate strain of composite laminate can be monitored using DIC in real time. And, the failure location can be predicted from the full-field interlaminate strain. DIC method provids an effective tool for strain monitoring of interlaminate shear properties of composite laminates.

Key words: composite laminate, interlaminate shear properties, digital image correlation, full-field deformation, ABAQUS
