Static Three-Point Bending Tests on 3D Printed Multilayer Composite Plates
The article presents the results of static tests for three-point bending of composite three-layer plates with continuous outer layers and tetrachiral honeycomb core. The plates were made using 3D printing (stereolithographic printing), and the procedure of laboratory additive manufacturing has been described in detail. Four series of samples were tested, varying in the discretization (number of elementary cells) of the filler. Samples within the series differ in the thickness of tetrachiral honeycombs, but the volume of their solid body is the same. As a result of the tests, graphs of the displacement dependence of the load were obtained. It has been shown that the thickness of the honeycomb core significantly affects the strength of the composites, despite the decrease in the thickness of the ribs of the honeycomb core, namely: the thicker the sample, the greater the bending strength it has, even with the decrease in the thickness of the walls of the honeycomb core ribs.
