3D Printing of Ceramic Elements with Q-Surface Geometry for the Fabrication of Protective Barrier

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 densi...

Zusammenfassung: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 ρap = 3.6 g/cm3, open porosity Popn = 8.5%, microhardness Hµ = 15.3 GPa, water absorption W = 2.4%, elastic modulus E = 405 GPa. The Stiglich criterion M = 1.72 EPa2·m3/kg, and the Shevchenko criterion K = 0.8.
