摘要
Acoustic cores and methods for forming and for assembling acoustic cores are provided. For example, an acoustic core of a gas turbine engine comprises a first attenuation section having a first plurality of attenuation members and a first mating wall having a planar first mating surface. The first mating wall is integrally formed with at least a portion of the first plurality of attenuation members and defines a portion of a perimeter of the first attenuation section. A method for forming an acoustic core comprises additively manufacturing a first attenuation section of the acoustic core, which comprises a first plurality of attenuation members and a first mating wall that are integrally formed as a single unit. A method for assembling an acoustic core comprises applying an adhesive to mating surfaces of first and second attenuation sections and pressing together the mating surfaces to join the first and second attenuation sections.
