INTERVIEW: Kai André Weidenmann, 3rd place at the poster presentation during the Verbundwerkstoffe Congress in Vienna

Dr.-Ing. Kai André Weidenmann, Karlsruher Institut für Technologie (KIT). The Edge Shear Test - an Alternative Testing Method for the Determination of the Interlaminar Shear Strength in Composite Materials

Can you give a brief summary of your poster presentation?

The poster deals with the edge shear test as a novel method to determine the interfacial shear strength. This characteristic value for composite materials is quite often determined by the ILSS which is known to be not a very reliable method but featuring the advantage of a very simple specimen geometry. Other methods described in literature need very elaborate sample preparation. With the test rig presented in our poster, we tried to merge the advantages of all methods and to overcome the shortcomings.

How did you feel when found out that you were awarded the prize? 

The problem in measuring the interlaminar shear strength is a well-known one in composite science, Hence, we were thrilled when we found this alternative method and the developed test rig working for the determination of the interlaminar shear strength for the compsoites we investigated at that time.

How was your experience at the Verbundwerkstoffe Conference?

The Verbundwerkstoff Conference is attractive in its familiar atmosphere. Almost all experts of the German-speaking community in composite materials are meeting every two years to discuss about current issues in research. The conference covers nearly all aspects, such as production, characterization and modelling of composites based on polymers, metals and ceramics. Since I have taken part the first time in 2005 in Kassel as a doctoral student, I have joined this conference every two years and could see the increasing importance of this field of research

What would you like to see in the next Verbundwerkstoffe Conference? 

First of all, I would like to see all my fellow colleagues again in Bremen! Joking apart, I would appreciate to see more participants from the field of polymer composites and manufacturing research. The relationship between processing, microstructure and properties is the basis of materials science, hence it would be good to have all aspects represented in the contributions. 

Which is the implication of this prize on your career?

For me, it is an honour to get this price at a quite advanced stage of my career. I know, that this award is more or less dedicated to junior scientists and I did not really expect to be awarded.

Which are your plans for the future? Publications? Working in the Industry? At Universities? 

My plans are to continue my university career. At the moment, I am heading a workgroup with roundabout ten scientists working on the materials science of composite materials with a focus on in-situ-characterization. I hopefully have the opportunity to continue this work in a successful manner.
