3D PRINTED ACOUSTIC PANEL WITH LATTICE STRUCTURE SUPPORT LAYER
In some examples, acoustic panels (such as for gas turbine engines) and techniques for forming acoustic panels. In some examples, the acoustic panel including a coversheet including an outer face, an inner face, and a plurality of apertures extend from the outer face to the inner face. The acoustic...

| description | In some examples, acoustic panels (such as for gas turbine engines) and techniques for forming acoustic panels. In some examples, the acoustic panel including a coversheet including an outer face, an inner face, and a plurality of apertures extend from the outer face to the inner face. The acoustic panel also includes a 3D-printed support layer including a lattice structure formed at least partially of a polymer, the lattice structure defining a plurality of cells of the support layer, wherein a first side of the support layer is coincident with the inner face of the coversheet. |
