Description
Summary:The work proposes the use of aluminum oxide-based ceramic objects with a TPMS-Q-surface geometry as elements of armor structures. The samples were produced using the SLA-DLP 3D printing method. The main properties of the sample were determined using physical-chemical analysis methods: apparent density ρ<sub>ap</sub> = 3.6 g/cm<sup>3</sup>, open porosity P<sub>opn</sub> = 8.5%, microhardness H<sub>µ</sub> = 15.3 GPa, water absorption W = 2.4%, elastic modulus E = 405 GPa. The Stiglich criterion M = 1.72 EPa<sup>2</sup>·m<sup>3</sup>/kg, and the Shevchenko criterion K = 0.8.
