Vita Thomas Neumeyer

Professor Neumeyer, born in 1983, studied precision engineering / mechatronics at the Munich University of Applied Sciences and graduated in 2010.

He then worked as a research assistant at the Chair of Polymer Materials at the University of Bayreuth from 2010 and also as head of the Thermosets and Fiber Composites working group there from 2012.
In 2015, he completed his doctorate under Professor Volker Altstädt on the topic of "Structure and properties of new, flame-retardant prepreg matrix systems for applications in the cabin of commercial aircraft".

From 2015 to 2023, Professor Neumeyer headed the Polymers Business Unit of Neue Materialien Bayreuth GmbH. His areas of work included the topics of fiber-reinforced plastics, particle foams, special injection molding processes and additive manufacturing with plastics. In addition, sustainability aspects and their quantitative evaluation represent a cross-cutting theme of his work. In addition, he was a lecturer at the University of Bayreuth in the subject "Polymer Composites" and a member of the expert panel "Additive Manufacturing" at the Bavarian State Ministry of Economic Affairs, Regional Development and Energy. From July 2016 to December 2022, in addition to his work at Neue Materialien Bayreuth, he was also Managing Director of the industry network for polypropylene particle foams "EPP-Forum e.V.".

Since September 2023, he has been appointed Research Director of the Program Area Manufacturing Science of  Leibniz-Institut für Verbundwerkstoffe as well as University Professor at the Rhineland-Palatinate Technical University Kaiserslautern-Landau.
