Composites

Composite materials, particularly within the aerospace industry, have been a primary area of application for air-coupled (and dry-coupled) test methods. The following are among the examples of results from inspection of composite parts.

These are all through transmission C‑scans obtaining results which will be reasonably familiar to users of conven­tional ultrasonic testing, however many production inspections can conveniently use a plate wave configuration, giving simple “go/no go” quality assessments. This has been particularly applied to pultruded composites.
