AI-COUPLED UT - CONTACT-FREE TESTING OF COMPOSITES

Due to the smaller impedance differences to the air, air-coupled ultrasonic testing works,physically and practically, in most cases better on plastic and composite components than onmetallic materials. In addition, there are often no established or at least no efficient testmethods for plastic and composite components, since their material- or production-dependentproperties often do not allow contact with liquid coupling agent or are at least highlydisadvantageous.This does not fundamentally exclude metallic materials for air-coupled ultrasonic testing, butclearly puts the focus on:

Plastic and composite components such as carbon or glass fiber reinforced plastics (CFRPand GFRP)

Honeycomb structures with different core and top layer materials

Rubber, foams, etc.

Ceramic and concrete materials

WoodTYPICAL FLAWS

Typical flaws include all types of volume defects such as delamination, in particular kissingbonds in the case of bonded materials, dry / non-wetted fibers, and cracks and inclusions of airor foreign matters. The advantage of air-coupled ultrasonic testing is that defects can not onlybe detected, but in some cases a certain degree of the error can be determined.

The smallest detectable flaw size is currently around 1.00 mm for isolated individual errors.However, previous investigations have already succeeded in finding significantly smallererrors. The size of the defects that can be detected and the transmission capability differwidely and depend in particular on the material dimensions, the type of defect and theproperties of the material. A general statement cannot be made in most cases. In any case, itis important to carry out a preliminary examination or a feasibility study.
