Abstract
Systems and methods are provided for fabricating acoustic panels. One embodiment is a method comprising acquiring a core of acoustic cells, and fabricating a facesheet covering the core by: dispensing a base layer of material atop the acoustic cells while leaving openings into each of the acoustic cells, covering the openings by applying a liner of porous material atop the base layer, dispensing a cap layer of material atop liner while leaving gaps in the cap layer over the acoustic cells, and fusing the cap layer to the liner by directly radiating laser energy onto locations where the cap layer has been dispensed.
