Research Activities
Experimental Micromechanics of Composites(1988~present):In-situ microscopic failure observation techniques were developed using several microscopes (SEM, TEM, SAM and so on.) with loading apparatus to quantify the microscopic failure process in composites, and then theoretical modeling was developed based on these observations.

Smart Composite Structural Health Monitoring (1988~present): Optical fiber sensor based structural health monitoring systems are being developed and applied to aerospace composite structures in practical applications.
