Research Interests
Microcellular Foaming: Foaming process can be performed in extrusion and injection molding to obtain low-weight final products with unique properties such as thermal insulation and impact absorption. Microcellualr foams are characterized by very small cells in the order of 10 micron. This unique structure will impart higher mechanical and physical properties. My main interest is to further investigate the mechanical and physical properties of these materials produced in injection molding. Specifically in injection molding process, achieving a sound microcellular structure is highly challenging. The relationship between microstrural and mechanical properties are also of my research interest.
Advanced and Green Materials- Wood Plastic Composites (WPC): WPC, recognized as a “green material” are one of the fastest growing segment of composite materials used mainly in the construction industry. My main interest is in properties development, production, die design in order to achieve higher performances. Extrusion process and injection molding are the principal methods utilized for production of WPCs. Due to their unique properties, they demand new approaches in die design. Foaming process is also incorporated in order to achieve lighter final products. The new development is to incorporate additional reinforcing component (long fibers such as glass and Kevlar) and rubber in order to enhance final mechanical properties in order to make them suitable for load bearing application (their current point of weakness)
Visualization: Visualization is an effective technique in understanding physical phenomena. In particular, visualizing polymer processes is a highly interesting research topic which enhance our knowledge of polymer processes. My main interest is injection molding process where a special mold is designed to provide a window to visual a high speed process of mold filling. Mold filling process, orientation (such as fibers), foaming process (cell nucleation and growth) can be analyzed via this technique. A high speed camera equipped with appropriate data collection hardware and software is required for this research work. Also, another area of research work is visualizing the fracture mechanism in composites (specifically on wood plastic composites).
Modeling and Simulation (of Plastic Materials and process): Simulation of shrinkage in injection molded parts and failure analysis in particle reinforced plastics are of those topics which I have worked and am interested to conduct researches. While experimental works have their high merits and advantages, it is also necessary to understand the fundamental via simulation and modeling.
