3rd Place at 27th Saxon Prize Award in Forming Technology 2021
01. April 2021
The Dr. Rolf Umbach Prize has been offered and awarded every year since 1995 to promote innovative accomplishments of junior up-and-coming researchers in the field of forming engineering.
The prizes were awarded virtually this year within the agenda of the 27th Saxon Expert Convention on Forming Technology on the topic of “Contributions of forming engineering to sustainable mobility”.
Jost Zubrytzki, graduate from the Dresden University of Applied Sciences in the subject of Production Engineering (Hochschule für Technik und Wirtschaft (HTW)), was rewarded with the 3rd place at the 27th Saxon Prize for Forming Technology for his diploma thesis supervised by the Institut für Holztechnologie Dresden (IHD) on the subject: “Investigations into the compression of birch veneer and its influence on selected strength properties”.
His diploma thesis is based on a patent by Dr.-Ing. Wilhelm Klauditz. In this patent, a process describes poplar veneer being chemically treated, merely cold-compressed and subsequently dried. Within the scope of his thesis, this process was successfully reproduced at the IHD. In his efforts, he was supported by colleagues from IHD’s Chemistry Area (Sebastian Kniep, – chemical pulping and processes, Dr. Martin Fischer – provision of basic literature), Materials Area (with its press technology and expertise) as well as Physics Area (Ms. Faust – sample material testing,
Ms. Bogatzki – mixing of the lye, Mr. Feuersenger – expert and practical supervision).
On the part of the HTW, Mr. Zubrytzki received support from Professor Lutz Lachmann (Dr.-Ing.) from the Faculty of Production Engineering in tackling the topic.The results in the material obtained yielded indications of
- the transferability of the inhomogeneous into a quasi-homogeneous wood structure,
- a considerable increase in tensile strength by more than threefoldas well as
- an increase in bending strength by approx. 50 %,
which proved the success of the process or its modification, respectively.
In addition, the modified material showed a significant gain in flexibility and pliability. As part of the diploma thesis, a wave geometry could successfully be introduced into the material during compression. Furthermore, the tensile strength of the birch veneer could greatly be raised by modification, which now allows the material to compete with a range of metallic and non-metallic materials.
