Composite Seminars

Professional seminars and trainings regarding testing of fiber-reinforced plastics


Regarding the topic of material testing of fiber-reinforced plastics, Grasse Zur Composite Testing offers a number of interesting professional seminars and training opportunities. The trainings are taking place in our head office in Berlin close to our accredited test laboratory. They generally consist both of a theoretical and a practical part, including the experimental testing of composite materials. Please note that we have limited numbers of participations to guarantee a higher quality for the professional trainings.

Calender 2022

The professional seminars offer the time and opportunity to make contacts and to discuss everyday challenges and questions. After the first day of the event, the discussions can be continued in a pleasant atmosphere during dinner.

Due to the current COVID-19 pandemic, the restaurants in the federal state of Berlin are closed by law, so that the joint dinner cannot take place after the end of the first day of the event. We apologise for this.

Seminar Lecturers

Grasse Zur Composite Testing offers a series of professional seminars and training courses on the subject of material testing of fibre-reinforced plastics. The company cooperates with lecturers who have gained their many years of experience in research and development.

The lecturers can be contacted at any time before and after the professional seminars. Just get in touch with us.

Dr. rer. nat. habil. Wolfgang Stark

Dr. Wolfgang Stark studied physics at the Humboldt-Universität Berlin. After completing his research studies in semiconductor physics, he was awarded his doctorate in 1975. In the same year he joined the Institute of Polymer Chemistry of the Academy of Sciences in Teltow-Seehof as a research assistant in the field of polymer physics. After his initial occupation with infrared spectroscopy, he switched to the electret group and developed methods for electret applications in microphones and sensors. He habilitated in this field in 1985. A new field of work was mechanical testing including DMA on synthetic high-temperature fibers.

In 1991 he became a scientific assistant at the Federal Institute for Materials Research and Testing (BAM) in the laboratory for thermosets. The focus was on the continuation of the traditional monitoring of the production of thermoset parts for the electrical industry and the award of the quality mark. This also included the development of methods for process control with dielectric and ultrasonic measuring methods. Together with partners from industry and the AVK e.V. Germany a number of joint research projects were carried out. In 1998, the project group, consisting of ISK Iserlohn, Bakelite Letmathe and BAM, was awarded the AVK Innovation Price for the development of online process control US-Plus. From 2006 onwards, he headed the elastomere reference materials laboratory at BAM with its own elastomer pilot plant.

Dipl.-Ing. (FH) Clemens Judersleben

Clemens Judersleben studied production engineering at the Dresden University of Applied Sciences. During his studies he spent time abroad at the National Taiwan University and at the National University of Science and Technology Trondheim. Since August 2017 he is head of the materials testing laboratory of Grasse Zur Composite Testing.

He has extensive experience in the field of destructive testing of fiber-reinforced plastics and thermal analysis. Due to his working environment, he has a broad knowledge of universal testing machines and a comprehensive overview of DIN, ISO and ASTM standards.

Dr.-Ing. Marc Prewitz

Dr. Marc Prewitz studied materials science at the Technical University of Berlin. After a long period of employment as a student assistant at the Institute for Research and Development of Sports Equipment (FES), he worked as a test engineer. He then moved to the Federal Institute for Materials Research and Testing (BAM) and completed his PhD in the field of high-pressure hydrogen storage.

After his PhD, he moved to the Department of Aircraft Construction and Lightweight Design at the Technical University of Berlin. Since then he has been working there as a research assistant and, among other things, supervises the course “Fatigue strength of lightweight structures made of metallic and fibre composite materials”.

Dipl.-Ing. (FH) Axel Reinsch

Axel Reinsch first completed an apprenticeship in composite boatbuilding receiving his certificate of apprenticeship in 2000. Having established a solid foundation in engineering, he went on to study aircraft construction with a focus on structural design and composites. In 2005 he completed his studies with his diploma thesis at the DLR (German Aerospace Centre) / CRC-ACS (Cooperative Research Centre for Advanced Composite Structures). After his studies, Axel Reinsch went on to work at Airbus for two years. As a structural engineer he took part in the A380 rudder program, as well as the A350 wing program, working in England and Germany. Afterwards he went on to Valencia/Spain, where he supported the German Americas Cup Team as a structural designer.

When the team was disbanded in early 2008, he switched to Swiss-based Carbo-Link. Here he operated as a developmental engineer, successfully working on projects with partners such as Alinghi, BMW-Sauber F1 or Liebherr. In addition to that, he developed high-end lightweight products in titanium, aluminium alloy and carbon. After returning home in spring of 2010, he founded ar engineers with its offices in Hamburg.

Dipl.-Ing. Udo Koensgen

Udo Koensgen is a VDI-certified examiner and trainer according to VDI/VDE 2636 for levels 1-3. The VDI guideline covers the area of experimental strain and stress analysis using strain gauges. He has been working voluntarily for VDI for many years and, together with other experts from industry and various universities, is revising the VDI guidelines in the field of strain measurement technology. He conducts basic DMS seminars for Micro-Measurements GmbH on the basis of VDI/VDE/GESA 2636 guidelines. A constant exchange about new developments in the field of strain measurement technology is a must for him. He has been working for Vishay Micro-Measurements GmbH in sales since 2011. Vishay is a manufacturer of strain gauges, data acquisition systems and accessories. Through his expertise he advises customers and users in many areas of aerospace, automotive, medical technology, materials testing etc.

Udo Koensgen is a trained electrical mechanic, a state-certified electrical engineer with a focus on energy technology and process automation, and a civil engineer with a focus on structural engineering. His diploma thesis deals with the “Structural investigation of a carrier plate” by means of strain gauges and FEM. His professional career at TUEV Rheinland, AVL-Schrick GmbH and Vishay Micro-Measurements GmbH has always focused on measurement technology.
