Abstract
Three-point bending tests on glass-fiber reinforced polymer GFRP/Kraft honeycomb sandwich panels after natural aging were undertaken to explore the bending performance of composite honeycomb sandwich panels after long-term aging. The specimens’ failure modes and ultimate damage patterns were recorded, and the pertinent data from the tests were statistically analyzed. A finite element model was developed to investigate the process of fiber failure based on the Hashin failure criterion. The results showed that the bending performance increased significantly, with a small dispersion of the test data; the specimen failure forms were consistent with expectations; the failure mode and result of FEM are in general agreement with the tests.
