Özet

This study investigates the effect of different temperatures on the flexural properties of honeycomb sandwich structures which have a commercial code as Gillfloor 5424. Flexural properties of honeycomb sandwich structures were determined under three different temperatures (-20 degrees C, 20 degrees C, and 40 degrees C). The results obtained from honeycomb sandwich structures were correlated with a function of core shear ultimate stress, facing stress, flexural stiffness and bending modulus of the sandwich panel. Moreover, cone beam computed tomography technique was used to visualize the internal damage of honeycomb sandwich structures after three point bending tests. POLYM. COMPOS., 39:46-54, 2018.
