Abstract: A method and system for visualizing the effects of corrosion are provided. In the context of a method, a workpiece is interrogated with radiation, such as by interrogating the workpiece with x-ray radiation. By relying upon a radiographic technique, the workpiece may be hidden and may be interrogated without disassembly. The method generates a backscatter image of the workpiece based upon radiation backscattered from the workpiece. The method also compares one or more regions of the backscatter image of the workpiece with respect to backscatter images of different metal loss indicators. Each metal loss indicator is representative of a different amount of metal loss. As a result of the comparison, the method estimates the metal loss attributable to corrosion of the workpiece.

Abstract: The operation of tow cutters in an automatic fiber placement machine are monitored to determine if inconsistencies in fiber placement are related to cutter operation. A machine vision system detects inconsistencies in tow placement, and timing signals are generated that represent the actuation of the cutters. The timing signals are correlated with recorded images of the placed tows to determine if the inconsistency in tow placement is related to cutter operation.

Abstract: Methods for determining an inconsistency characteristic of a composite structure, such as inconsistency density-per-unit area. In one implementation, a method is disclosed for determining an inconsistency characteristic of a composite structure. The method involves determining a first distance from a first reference point of the composite structure to an inconsistency; determining a second distance from a second reference point of the composite structure to the inconsistency; using the first and second distances to establish a reference area of the composite structure; and considering each inconsistency detected within the reference area and producing therefrom an inconsistency characteristic representative of the composite structure.
