Lightweight, energy absorbing materials are of great interest in numerous engineering applications particularly where vibration damping/noise or impact resistance are important. Incorporation of new paradigms in developing materials is necessary to overcome the challenges involved in establishing novel solutions to meet the demand. In this seminar, two types of composite materials will be discussed. Firstly, particulate polymer composites with significantly enhanced tensile toughness as well as low-velocity impact properties are introduced. The seminar will cover the fabrication, characterization of tensile properties and the investigation on the identification of the responsible mechanisms for the improvement in the toughness. Also low-velocity impact properties will be discussed compared to the neat polymer matrix material. Secondly, natural cork employed sandwich composite materials will be introduced. The compressive behaviors of cork will be presented, which are shown to be highly recoverable. The noise-free and high damping properties of the sandwich composites will be presented, which still remain uncompromised in mechanical bending stiffness. In addition, low-velocity impact behaviors of cork-core carbon fiber sandwich composites will be highlighted and compared to the rohacell-core sandwich composites.
Bio: Jonghwan Suhr is currently an associate professor of Polymer Science & Engineering at Sungkyunkwan University (SKKU). He was previously an assistant professor of Mechanical Engineering at the University of Delaware and also an affiliated faculty member in the Center for Composite Materials (CCM) from 2010 to 2013. He was also working as an assistant professor of Mechanical Engineering at the University of Nevada, Reno from 2007 to 2010. He received his Ph.D in mechanical engineering from Rensselaer Polytechnic Institute (Troy, NY) in 2005. He performed post-doctoral work at the NYS-Focus Center in Rensselaer (2005-2006). Dr. Suhr’s research interests include energy absorbing composites, lightweight multifunctional composites, and 3D printing materials. An advocate of interdisciplinary research, his work focuses on composite materials, mechanical engineering, aerospace structures and bio-mimetics that impact structural applications to stimulate scientific discovery, support novel material development, advance future aerospace technologies, facilitate technology transfer and enhance student learning.
In 2009, he received an NSF CAREER Award. He is a member of ASME, SPIE, and SAMPE. He is also serving as a technical committee member for ASME adaptive structures and material systems and an editorial board members for Nature Scientific Reports.
