SYSTEM FOR HIGH SPEED SURFACE AND SUBSURFACE FOREIGN OBJECT DEBRIS AND DEFECT DETECTION

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 (203, 205, 215, 220, 305) moves over the composite part (140, 201) along a predetermined length ther...

Beschreibung
Zusammenfassung:	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 (203, 205, 215, 220, 305) moves over the composite part (140, 201) along a predetermined length thereof. A thermal excitation source (110) fixed to the gantry (203, 205, 215, 220, 305) directs infrared radiation across the width of the surface of the composite part (140, 201). An infrared camera (120, 206, 210, 211, 212, 216, 221, 310, 320, 330) fixed to the gantry (203, 205, 215, 220, 305) a predetermined distance away from the thermal excitation source (110) scans the surface as the gantry (203, 205, 215, 220, 305) moves to detect and output scan information thereof. A controller (170) is coupled to the thermal excitation source (110) and to the infrared camera (120, 206, 210, 211, 212, 216, 221, 310, 320, 330). The controller (170) processes the sequence of infrared images to identify a foreign object debris material or defect located on and/or under the surface.
