Q: Please introduce yourself. What are your responsibilities within your company SONOTEC?

A: Hello, my name is Henning Korngiebel and I’m the Non-destructive Material Testing Sales Engineer for SONOTEC. My duties include determining market and customer requirements, visiting clients and developing solutions to their non-destructive testing equipment needs.


Mr. Henning Korngiebel, SONOTEC

Q: Could you give us a quick overview of your company SONOTEC?

A: SONOTEC, founded 1991, is a growing technology company that provides specific solutions using ultrasonic measurement technologies. With more than 120 employees, of that 28 in R&D, we develop and produce our entire range of ultrasonic technologies in our own laboratories and production site.

We offer customer specific as well standard solutions for a variety of industrial applications, such as medical and pharmaceutical industries, petroleum industries, mechanical and plant engineering, automation technology and most important, non-destructive testing.

Q: You will exhibit the first time. Has your company always worked in the field of composites?

A: Last year we visited the COMPOSITES and it became apparent that quality control and material testing is yet relatively sparsely represented. SONOTEC will exhibit a composites testing system using ultrasonics that we have been developing for several years.  Therefore we are kind of an exotic exhibitor since we do not present composites but an air-coupled system to test composites.

Furthermore, SONOTEC has more than 20 years’ experience implementing customer-specific solutions for measuring and testing equipment. We even have our own manufacturing facility for Piezocomposites representing the centerpiece of an ultrasonic sensor.

Q: What kind of projects have you undertaken for clients?

A: We developed for customers from the R&D field a modularly designed air-coupled ultrasonic NDT Test System that facilitates the non-destructive, contactless testing of composites made of carbon and glass fiber-reinforced plastics (CFRP, GFRP) as well as steel and aluminum.

Typical examinations are the inspection of adhesive connections for multi-skin polycarbonate sheets, the testing of bubble films in order to check the uniform filling of the bubbles, and the examination of wood composite materials and composite materials in aircraft construction. This new testing system will be presented at the COMPOSITES.


Q: Looking to the future, where do you think the composites industry is headed? What are you looking forward to seeing?

A: The importance of composites increases due to the significance of lightweight constructions and omnipresent weight savings issues. Hence, there is indeed growing demand in the materials testing market.

In the past, ultrasonic testing was actually arisen from the need for metal testing. Currently new methods are developed for the testing of other materials such as GRP, CFC, honeycomb structures and expanded plastics.
