WOT receives poster award during the DGM Composites Expert Days
More than 70 participants from science and industry exchanged ideas during the online „Expert*innen-Tage Verbundwerkstoffe“ of the DGM on 29 and 30 June 2021. At this event, WOT employee Sarah Hirsch received the „Best Oral-Poster Award“ from an expert jury.
In addition to half-hour specialist presentations, the event also included a detailed oral presentation of visually and content-wise prepared posters. From a total of 28 presentations, the best three contributions were honoured with the „Best Oral-Poster Award“. The Chair of WOT was represented with a poster by Sarah Hirsch, Robert Pippig, Dr. Thomas Grund and Prof. Thomas Lampke on the topic „Influence of metal matrix powder size on toughness of a high reinforced aluminium matrix composite prepared by field assisted sintering technique”. Ms Hirsch presented the paper and convinced the expert jury.
In the article, process-related possibilities for improving the toughness of AMC materials with SiC as a reinforcing component were investigated. Based on practical applications, a comparatively high reinforcement content of 35 % SiC by volume was selected. The AMC materials were produced using FAST sintering (field-assisted sintering). In the course of production, different fractions of the aluminium powders used in the initial powder mixtures were used based on technical material considerations, and the manufactured samples were tested for toughness. The tests, which were planned, carried out and analysed according to statistical criteria, showed a high dependence of the characteristic values on these starting fractions.
Further information on the results can be obtained from the authors and can also be found in the WTK publication on the same topic ( https://iopscience.iop.org/article/10.1088/1757-899X/1147/1/012020 ).
