Abstract: A system and method for the detection of foreign object debris materials or defects on and/or under a surface (e.g., outer ply) of a composite part being formed by a composite layup machine. A gantry moves over the composite part along a predetermined length thereof. A thermal excitation source fixed to the gantry directs infrared radiation across the width of the surface of the composite part. A infrared camera fixed to the gantry a predetermined distance away from the thermal excitation source scans the surface as the gantry moves to detect and output scan information thereof. A controller is coupled to the thermal excitation source and to the infrared camera. The controller processes the sequence of infrared images to identify a foreign object debris material or defect located on and/or under the surface.

Abstract: Methods for identifying and quantifying wrinkles in a composite structure by processing infrared image data. The intensity and first and second time derivatives thereof at a particular time can be displayed as thermography line profiles on a graph in which the horizontal axis represents the pixel number across the field of view of an infrared camera. The spatial derivatives of the foregoing thermography line profiles can also be calculated and displayed as a graph. The maximum amplitude (i.e., height) of an out-of-plane wrinkle can be determined using a correlation/calibration curve that is constructed by correlating infrared image data with optical measurement data. In addition, the wavelength and maximum amplitude of an in-plane wrinkle can be measured directly from the thermography line profiles.

Abstract: An infrared (IR) thermography system for inspecting porosity of a test part of a given thickness is provided. The IR thermography system may include a thermal detector configured to detect IR signals emitted from the test part, and a controller in electrical communication with at least the thermal detector. The controller may be configured to at least determine thermal test data associated with the test part based on the IR signals, generate thermal model data based on the thickness of the test part, and determine porosity of the test part based on a comparison between the thermal test data and the thermal model data.

Abstract: A method for determining an actual shear angle between an interior wall and a facesheet of a cellular panel using an imaging system is disclosed. The imaging system may include a radiation source and a detector diametrically opposed to the radiation source. The method may include positioning the cellular panel at a tilt angle relative to a line extending between the radiation source and the detector, transmitting radiation from the radiation source to the detector through the cellular panel at the tilt angle to obtain an image, measuring a projected shear angle in the obtained image, and determining the actual shear angle between the interior wall and the facesheet using the tilt angle and the projected shear angle.

Abstract: Methods for identifying and quantifying wrinkles in a composite structure by processing infrared imaging data. Temperature versus time profiles for all pixels in the field of view of an infrared camera are calculated, enabling thermal signatures to be produced. By comparing the thermal signature of the part under test with the thermal signature of a reference standard representing a similar part having wrinkles of known size and shape, the presence of wrinkles can be detected. The wrinkle wavelength can be determined by measuring the infrared image and applying a transfer function. If the geometric information acquired using infrared thermography does not reach a certain quality factor (for a quality prediction) or is incomplete, an ultrasonic transducer array probe running wrinkle quantification software can be rotated into position and scanned over the wrinkle area. The ultrasonic imaging data can be combined with the infrared imaging data to enable an improved quantification of the wrinkle geometry.

Abstract: A system for the detection of foreign object debris material on a surface of a composite part being manufactured. A platform is configured to move over the surface. A thermal excitation source is fixed to the platform and configured to direct infrared radiation across the surface. An infrared camera is also fixed to the platform and configured to scan the surface as the platform moves over the surface to detect and output a signal proportional to infrared radiation emitted by the surface and/or by any foreign object debris material on the surface in response to the infrared radiation from the excitation source. A controller is coupled to the excitation source and to the infrared camera and is configured to compare the signal from the infrared camera with a first predetermined threshold signal to detect if any foreign object debris material is located on the surface.
