Tensile Test of Composite Laminates and Specimen's Improvement

Abstract:

To obtain the material parameters for the composite laminate structure based on the general strength theory and failure criterion, a series of strength experiments are required to be carried out for some typical laminated fiber reinforced composite laminate plate. Due to complexity of stress state of specimen, some unexpected failure modes will often appear in the tensile test process of composite laminated plate. In this paper, according to the tensile test, the analysis for the failure mechanism of the specimen was executed by using finite element method. The suggestion for suitable geometry of the specimen was put forward, and the experimental results proved that the improvement for the specimen design was effective, thus the success rate of test was improved.
