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 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.

Abstract: Methods are presented. Signals are sent into a first surface of a structure using an ultrasonic transducer. Ultrasound response signals are received at the ultrasonic transducer. A portion of a second surface of the structure is heated while the ultrasonic transducer is sending signals into the first surface, wherein the second surface is on an opposite side of the structure from the first surface. Infrared images of the portion of the second surface of the structure are taken after heating the second surface.

Abstract: Provided is an inspection apparatus that includes a rotation disk configured to spin about an axis of rotation. The rotation disk includes a probe bushing configured to securely hold a standard eddy current probe a predetermined distance above a surface to be examined by the probe. The rotation disk is further configured to adjustably hold the standard eddy current probe such that the radial offset of the probe from the axis of rotation is set using a radial positioning set screw that is coupled to the rotation disk via a first slotted arm. The predetermined distance is set using a probe height set screw configured to secure the probe within the probe bushing. An outer stationary housing is coupled to the rotation disk such that the rotation disk rotates within the outer stationary housing.

Abstract: An optical scanning assembly for use in inspecting a channel is provided. The assembly includes a housing and an inspection probe that selectively advances from the housing along an axis. The probe includes a light source that directs light towards at least one side wall of the channel and a light detector that receives the light reflected from the side wall. The assembly further includes a controller in communication with the inspection probe. The controller obtains a first optical length measurement for the light reflected from the side wall when the inspection probe is in a first position along the axis within the channel, obtain a second optical length measurement for the light reflected from the side wall when the inspection probe is in a second position along the axis within the channel, and compare the first and second optical length measurements to determine variations in a geometry of the channel.

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 system for the detection of foreign object debris material on a surface includes an ultraviolet light source configured to direct ultraviolet light across a surface. The surface is an outer surface of a composite part being formed by a composite layup machine. The system includes an ultraviolet light camera configured to scan the surface and output a first signal proportional to reflected ultraviolet light reflected by at least one of the surface and a first type of foreign object debris material. The reflected ultraviolet light is responsive to the ultraviolet light from the ultraviolet light source. The system also includes a controller coupled to the ultraviolet light source and to the ultraviolet light camera. The controller is configured to compare the first signal from the ultraviolet light camera with a first threshold to detect presence of the first type of foreign object debris material.

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.
