Auxetic lattice core, sandwich panel with an auxetic lattice core and method for producing a cellular plate with an auxetic lattice core

摘要

The object of the notification is an auximetric grid core containing no less than two asymmetrical periodic systems in which each of the systems contains four arms of any cross-section placed symmetrically on two mutually perpendicular planes that are bound in one apex, and such systems are perpendicularly, irreparably periodically inverted by the common top down or up, two adjacent systems are bound by the shoulders forming another irreparably periodic top, the structure displays cyclical periodicity only after the transverse parent structure,and in edges, the structures are irreparably periodic. A sheet with a lattice axis core containing at least three layers of construction, of which at least one layer is an outer layer permanently connected to a lattice axis core attached to a support layer, and the outer layer is full (1) The method of production of a cellular plate with a grid axial core is that the 3D core printer is placed between at least one coated polyoctane-vinyl glue containing 52% solids with an outer layer and a support layer,and glue shall be applied to at least one outer layer and support layer of no less than 120 g/m2, and the aggregated layer shall be pressed for at least eight hours at the temperature of 16-40 degrees Celsius under pressure 2,2 MPa (106 N/m2).
