Abstract: A defect visualization system includes an augmented reality viewing device including a display, and a visualization module configured to receive defect data representative of the defects on the part, determine a position of the augmented reality viewing device in relation to the part, generate one or more display objects, wherein each display object of the display objects corresponds to a respective defect of the defects, and present the display objects on the display so that the display objects appear in alignment with the defects on the part.

Abstract: A method of in-process inspection includes acquiring a grayscale image of an automated fiber placement (AFP) workpiece, executing a series of detection algorithms on the grayscale image to identify a plurality of characteristics in the grayscale image indicative of one or more defects in the AFP workpiece, and detecting the one or more defects in the AFP workpiece based on the identified plurality of characteristics.

Abstract: A tool for use with Automated Fiber Placement (AFP) machines and systems for use in in-process inspection of composite parts. The AFP system uses a robot, fiber guide, compaction roller, heating system, and an in-process inspection tool. The in-process inspection tool utilizes at least one profiler housed within a support bracket, which mounts the profiler on an AFP head of the AFP system such that the profiler does not interfere with the AFP layup, but outputs an in-process inspection signal representing a surface profile of a fiber strip as it is placed onto a molding for a composite part by the AFP head.
