| 제목 | DEVELOPMENT AND APPLICATION OF MULTIFUNCTIONAL POLYMER NANOCOMPOSITES |
| 초록 | The University of Dayton Research Institute (UDRI) has been conducting research in the development and application of polymer nanocomposites for over five years, with the primary focus directed at multifunctional aerospace applications. The purpose of this activity is two-fold: to develop multifunctional polymeric materials with enhanced thermal, electrical, barrier and structural properties that may be processed with traditional polymer processing equipment, and to develop a polymer matrix material that can significantly enhance the properties of conventional fiber-reinforced composites. Properties that are sought to be enhanced include damage tolerance, compression strength, shear strength, hot-wet properties, environmental durability, thermal conductivity, electrical conductivity, abrasion resistance, etc. The effort at UDRI is focused on demonstrating that conventional polymer and composite processing equipment and methods may be used to fabricate parts with these new materials. Nanostructured materials currently of commercial interest for polymer nanocomposites include vapor-grown, multi-walled carbon nanofibers, graphite flake, graphitic foams and layered silicates. Resin systems under investigation – primarily for aerospace applications – include epoxies and imide-based resins. This presentation will discuss recent successes related to: the treatment of these nanostructured materials to improve their dispersion in, and adhesion to the host polymer; dispersion of the nanomaterials in polymers to achieve uniform distribution at the nanoscale; development and scale-up of PNC formulations from batch sizes of 100 g to 100 lbs; tools and methods used to characterize these materials at the nanoscale, and the fabrication, testing and evaluation of conventional composites with PNC matrices. In addition the importance of partnering with key members of the technology value chain will be emphasized, to facilitate the smooth transition of this technology into commercial applications. This chain includes researchers, material suppliers, compounders, prepreggers, parts fabricators, and end users. This research, development and transition effort is supported by grants from the State of Ohio, while a variety of applications of these materials are being explored collaboratively with a host of industrial and academic partners. |
