Materials Inspection Effortless

Defects in the final product can quickly lead to malfunction and thus compromise safety massively – a challenge in many industrial areas such as automotive industry, aircraft, or steel construction. Hence, nondestructive inspection methods which allow to check components without destroying it take a key role in the quality assurance. From 21 to 25 October 2014, engineers of Fraunhofer IZFP in Saarbrücken provide two innovative methods on EuroBlech 2014 in Hannover which enable fast and reliable materials characterization (hall 11, booth C05).

They are invisible for the naked eye – yet tiny cracks or defects can cause fatal consequences, notably in safety-critical areas. Nevertheless, the demands on weight reduction rise even while the material must not be affected. To meet such requirement profiles, the use of new materials is required such as carbon or glass fiber-reinforced plastics (CFRP, GFRP), high-strength steels and light metals, often applied in combination with hybrid components.

Airborne ultrasound is a nondestructive inspection method which was successfully adapted for contactless and contamination-free materials inspection by engineers of the Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrücken. “Compared to competing products, the newly developed probes enable a higher testing frequency to realize an enhanced and optimized defect detection capability for thin materials inspection,” Dr. Thomas Waschkies explains, responsible engineer at Fraunhofer IZFP. “The improved design of the probes allows for a high sound level so that even strongly absorbing hybrid materials can be examined without contaminating them.” The functionality of this inspection technique and its relevance for different industrial areas are demonstrated and exemplified by Fraunhofer IZFP`s engineers at this year's EuroBlech in Hannover.
