Transcript – Advanced Mechanical Performances of Polymer Composites

Hi, thanks for your interest in our poster. This is a T3 project on advanced mechanical performance of polymer composites. This is a collaborative effort between Hung-Jue Su, Iman Borazjani and Lei Fang. We are interested in using modern, theoretical and experimental approach to accelerate the discovery of Next-Generation Polymer Composites with advanced mechanical performances. We’re particularly interested in inorganic and organic novel materials that serve as the filler for polymer composites. We use epoxy as the model polymer matrix for our investigation. So, for example, we were interested in NENO plate like zirconium phosphate and how does the liquid crystal and packing and how does the interface of the epoxy zirconium phosphate impacted the mechanical properties of the resulting composite? So we had some very encouraging result to have with increase the Young’s modulus of the polymer and also improved the tensile strength and those also associated with a higher glass transition temperature and they significantly reduced the thermal expansion coefficient. We also interested in novel organic compounds such as Krynica, all small molecules as the filler for epoxy in this project. Our hypothesis is that this rigid small molecule, small molecules could also serve as is highly, mechanically advanced filler. Experimentally, we have observed significant increase of tensile strength and indication that break by the addition of a very small amount of these all additives. We believe that this is due to the good dispersion of small molecules in the polymer matrix and this very nicely. Very nice blend. And good in the face of the small molecule and opponent matrix. Finally, we also using numeric Realogy simulation to investigate how the portable particle collision and also the geometrical factors of the Fiedler’s impact, the geological and mechanical properties of the parliament, the composite. And overall, we had some very exciting and encouraging results, and we appreciate the support from the T-3 and the president’s excellence fund for this collaborative project.
