Abstract
An acoustic treatment for use in an acoustic treatment for a gas turbine engine includes a sheath having a plurality of perforations. A plurality of cell structures extends from the sheath such that the sheath and the cell structures are a monolithic component. The plurality of perforations of the sheath are formed by filaments of a first material that define a first dimension of the perforations having a linear edge and filaments of a second material crossing the filaments of the first material that define a second dimension of the perforations having a linear edge. Such perforations have a non-cylindrical shape defined by the linear edges of the filaments of the first material and the filaments of the second material. A gas turbine engine is also disclosed.
