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: A system for nondestructive evaluation of a test object includes a platform, an electromagnetic acoustic transducer (EMAT) to create acoustic vibrations that travel along the test object; an infrared detector positioned to record thermal images of a plurality of test areas on the test object to detect flaws in the test object as the platform and the test object move relative to each other; and a control connected to actuate the EMAT and the infrared detector, synchronize the creation of vibrations with the recording of thermal images, receive a signal from the infrared detector indicative of the thermal image of the surface of the test object, and record locations of the flaws appearing on the thermal images of the test areas, all as the platform and the test object move relative to each other.

Abstract: A system and method for the detection of foreign object debris materials or defects on and/or under a surface of a composite part under manufacture. A member, for example an inspection gantry, is configured to move over the surface. A thermal excitation source is fixed to the member and is configured to direct infrared radiation across the surface. An infrared camera is also fixed to the member a predetermined distance away from the thermal excitation source and is configured to scan the surface as the member moves over the surface to detect and output scan information of the surface. A controller is coupled to the excitation source and to the infrared camera. The controller is configured to process the scan information from the infrared camera to identify a foreign object debris material or defect located on and/or under the surface.

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: Method and apparatus for detecting defects in a laminate of uncured, compacted composite sheets. After a number of plies of composite sheets are arranged and compacted, a burst of heat energy is applied to a top surface of the laminate and a digital thermographic camera captures images of the top surface. A computer processor measures heat characteristics of the top surface to identify regions of the top surface with different heat characteristics. Such different areas are identified as regions that include a defect. The defect regions can be repaired by applying additional compaction and/or by removing at least a portion of some layers, removing any foreign object debris, replacing the layers, and compacting the replaced layers. After any defects are addressed, the laminate is cured.

Abstract: Method and apparatus for detecting defects in a composite is provided. After a ply of material for a workpiece is positioned, thermal energy is applied to a top surface of the ply of material, and a digital thermographic camera captures images of the top surface. A computer processor determines heat characteristics of the top surface to identify regions of the top surface with different heat characteristics. Such different areas are identified as regions that include a defect. The defect regions can be repaired prior to disposing additional plies of material over previously-applied plies.

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: 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.
