W dniu 19 czerwca 2018 roku (wtorek) o godz. 14.00 w Audytorium – sala 1023 budynku UJD przy al.Armii Krajowej 13/15, odbędzie się Seminarium, w trakcie którego Prof. Patrick Navard z Centrum Kształtowania Materiałów CEMEF MINES ParisTech (PSL Research University, Sophia Antipolis, France) wygłosi wykład na temat: "Plant-based polymer composites" (Kompozyty polimerowe na bazie roślin).
Streszczenie wykładu:
This presentation will focus on the use of elongated plant fragments directly obtained after grinding plant stems for preparing polymer composites. We developed a robust method able to discriminate stem fragments according to their reinforcing capacity. We studied three genetically related crops: miscanthus, maize and sorghum. Fragments were collected on varied stem positions on 13 miscanthus genotypes of 7 to 9 years old, 10 sorghum genotypes selected among a panel of 396 genotypes and 10 genotypes of maize. This panel offers a very large range of plants from which stem fragments can be prepared.
The work focused on the relationships between the composition and histological structures of stem fragments and (1) the mechanical properties of the individual fragments, (2) their thermal stability and (3) the mechanical performances of polymer composites. Based on these analyses, we will be able to assess how the variability of plant structure and composition is influencing the final mechanical properties of polymer composites.
