    摘要： A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses onto an inner surface of a face sheet of an acoustic inner barrel. The acoustic inner barrel includes an acoustic core comprising an array of hexagonal cells attached to an outer surface of the face sheet that is opposite the inner surface. The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations in the face sheet via emitting laser pulses at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz.

    摘要： Systems and methods are provided for enhancing edge breathers for composite manufacturing. One exemplary embodiment is an apparatus that includes an edge breather to facilitate manufacturing of a composite part. The edge breather includes a body, ridges disposed along a length of the body that each define an arc which is perpendicular to a lengthwise axis of the body, and openings disposed along the body that enable air to enter a hollow interior that runs along the length of the body. The arcs defined by the ridges resist compressive loads applied to the edge breather and prevent the hollow interior from collapsing under pressure applied to the edge breather by a vacuum bag during manufacturing of the composite part.

    摘要： A forming system includes a femtosecond laser and a control unit that includes one or more processors operatively connected to the femtosecond laser. The femtosecond laser is configured to emit laser pulses onto an inner surface of a face sheet of an acoustic inner barrel. The acoustic inner barrel includes an acoustic core comprising an array of hexagonal cells attached to an outer surface of the face sheet that is opposite the inner surface. The control unit is configured to control the femtosecond laser to laser drill a plurality of perforations in the face sheet via emitting laser pulses at pulse durations between about 100 femtoseconds and about 10,000 femtoseconds and at frequencies over 100,000 Hz such that the perforations are formed without burning portions of the face sheet or the acoustic core surrounding the perforations.
