CHARACTERIZATION OF INTERLAMINATE SHEAR PROPERTIES FOR COMPOSITE MATERIALS USING DIGITAL IMAGE CORRELATION

Abstract

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
