DESCRIPTION:Prof. Jongwhan Suhr\, Department of Polymer Science & Engineer
 ing Sungkyunkwan University\, Suwon Korea\nLightweight\, energy absorbing 
 materials are of great interest in numerous engineering applications parti
 cularly where vibration damping/noise or impact resistance are important. 
 Incorporation of new paradigms in developing materials is necessary to ove
 rcome the challenges involved in establishing novel solutions to meet the 
 demand. In this seminar\, two types of composite materials will be discuss
 ed. Firstly\, particulate polymer composites with significantly enhanced t
 ensile toughness as well as low-velocity impact properties are introduced.
  The seminar will cover the fabrication\, characterization of tensile prop
 erties and the investigation on the identification of the responsible mech
 anisms for the improvement in the toughness. Also low-velocity impact prop
 erties will be discussed compared to the neat polymer matrix material. Sec
 ondly\, natural cork employed sandwich composite materials will be introdu
 ced. The compressive behaviors of cork will be presented\, which are shown
  to be highly recoverable. The noise-free and high damping properties of t
 he sandwich composites will be presented\, which still remain uncompromise
 d in mechanical bending stiffness. In addition\, low-velocity impact behav
 iors of cork-core carbon fiber sandwich composites will be highlighted and
  compared to the rohacell-core sandwich composites.\nBio: Jonghwan Suhr is
  currently an associate professor of Polymer Science & Engineering at Sung
 kyunkwan University (SKKU). He was previously an assistant professor of Me
 chanical Engineering at the University of Delaware and also an affiliated 
 faculty member in the Center for Composite Materials (CCM) from 2010 to 20
 13. He was also working as an assistant professor of Mechanical Engineerin
 g 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 R
 ensselaer (2005-2006). Dr. Suhr’s research interests include energy abso
 rbing composites\, lightweight multifunctional composites\, and 3D printin
 g 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
 .\nIn 2009\, he received an NSF CAREER Award. He is a member of ASME\, SPI
 E\, and SAMPE. He is also serving as a technical committee member for ASME
  adaptive structures and material systems and an editorial board members f
 or Nature Scientific Reports.
