인간은 몸에 분포되어 있는 신경망을 통해서 통증을 느낄 때, 치료를 받거나 병원을 찾습니다. 소재나 구조물에도 이러한 “신경망"을 부여하면, 외부 환경 뿐만 아니라, 변형, 파손과 같은 내부 상태를 감지할 수 있게 됩니다. FIMLab에서는, 2개 이상의 소재를 혼합하고 (복합재료), 소재 시스템을 구조적으로 설계함으로써 (“Material Systems by Design”), 구조건전성 자가센싱과 같은 스마트한 기능을 갖는 소재 및 구조물 연구를 수행하고 있습니다. 뿐만 아니라, 무거운 금속을 대체할 수 있는 경량 복합재료 제조 및 설계 연구도 수행하고 있습니다.
Dr. Park’s research interests are in the field of advanced composite and nanocomposite technologies for development of functional and intelligent materials and structures, that is, materials that “think” and “respond.”  In particular, his research focus is on the application of high-performance nanoscale materials, especially graphene and carbon nanotubes, to multifunctional composites and structures.  An example would be a “smart” automotive vehicle or aircraft that can self-sense its structural health, protect itself from external disturbances or hazards, and ultimately self-adjust or take necessary measures with minimal human intervention. More recently, Dr. Park has expanded his scope of research into novel technologies for rapid, affordable manufacturing of fiber-reinforced composites, particularly targeted for automotive industry. Currently, Dr. Park is serving as the director of the UNIST Composites Research Center in collaboration with Fraunhofer ICT.
