Özet
In this study, the low-velocity impact performances of sandwich composites in honeycomb geometry with three different cell widths and cell wall thicknesses but close surface areas were investigated. Three different cell width and cell wall thickness sizes of the core produced in the 3D printer and the cross-sectional views of the samples after the impact test are shown in Figure A.Purpose:The main aim of this study is to reveal the effects of different cell widths with similar surface areas on the low-velocity impact behavior of 3D printed sandwich composite test specimens.Theory and Methods:The cores of the sandwich composites were produced using a 3D printer using the additive manufacturing method. The tests of the samples were carried out according to the ASTM D7766 impact test standard by bonding the cores with CFRP plates. Impact behavior of samples with different cell widths at impact energies of 30J, 40J, 60J, 80J and 100J were presented with graphics and figures.Results:In the impact tests, as the impact energy increased, the damage height in the samples increased. While the striker perforated the top surface at 60J impact energy and damaged the core, it only damaged the bottom surface at 80J impact energy. At 100J impact energy, it completely perforated the sample.Conclusion:The behavior of the test samples produced in the 3D printer against five different impacts was determined.
