Abstract

A system and method for the analysis of composite materials in aircraft components. Structured light measurements are used to determine the 3-dimensional shape of an object, which is then analyzed to minimize the number of scans when performing laser ultrasound measurements.

Description

technical field [0001] The present invention generally relates to the field of non-destructive techniques for measuring composite materials. In particular, the present invention relates to methods and systems for correlating position data with ultrasound data. Background technique [0002] In recent years, the use of composite materials has grown in aerospace and other commercial industries. Composite materials offer significant improvements in performance, however, they are difficult to process and therefore require stringent quality control processes during processing. Non-destructive evaluation ("NDE") techniques have been developed as a method for determining defects in composite structures, eg, detection of impurities, delamination, and porosity. Traditional NDE methods are generally slow, labor-intensive, and costly. Thus, the testing process disadvantageously increases tooling costs associated with composite structures. [0003] For parts with irregular surfaces, ...
