  • Patent number: 10052723
    Abstract: Systems and methods for manufacturing laser-perforated nanoreinforced materials are disclosed. A honeycomb core may utilize a perforated top sheet and a microperforated overlay film coupled to the perforated top sheet. The perforated top sheet and/or the microperforated film may include thermally conductive nanomaterials. The perforations in the top sheet and the microperforations in the film may be laser drilled. The nanomaterials may dissipate heat generated by the laser drilling, allowing for increased perforation speeds.
    Type: Grant

  • Patent number: 10000277
    Abstract: An apparatus is provided for promoting laminar flow. The apparatus includes a panel extending between an interior surface and an exterior air flow surface. The panel includes a plurality of macro apertures and a plurality of micro apertures. A first one of the macro apertures extends into the panel from the interior surface. A first one of the micro apertures extends into the panel from the exterior air flow surface and is fluidly coupled with the first one of the macro apertures.

  • Patent number: 9950392
    Abstract: A process is provided for forming a plurality of apertures in a fiber-reinforced composite object using a laser. The apertures include at least a first aperture and a second aperture. During the process, a scanner head of the laser is operated from a location to selectively scan a laser beam over the object to form a first portion of the first aperture and to form a first portion of the second aperture. The scanner head is also operated from the location to selectively scan the laser beam over the object to form a second portion of the first aperture and to form a second portion of the second aperture.

  • Patent number: 9855626
    Abstract: A manufacturing method is provided which utilizes a laser system. During an embodiment of this method, an object is arranged relative to a head of the laser system. A pattern of holes are formed in the object by ablating the object with a plurality of laser beams which are directed from the head.

  • Patent number: 9447576
    Abstract: Acoustic panels and methods for manufacturing acoustic panels are provided. In one such method, a core structure is provided between and bonded to a top skin and a septum. A plurality of perforations are formed in the top skin using an energy beam device. A plurality of perforations are formed in the septum through the top skin holes using the energy beam device. A plurality of cavities in the core structure fluidly couple at least some of the perforations in the top skin with at least some of the perforations in the septum.
