Cutting/Drilling, Assembly, Operation Monitoring and Its Modeling

Strain monitoring is conducted through cutting/ drilling, assembly, and operation process using multiplexed FBG or distributed optical fiber sensor systems. Strain history can be an efficient way to prove the validity of various manufacturing processes. Theoretical and numerical modeling is also developed.


Fabrication Process Monitoring and Its Modeling

Thermal residual strain and temperature distribution of large-scale composite structures is monitored using optical fiber sensor systems. Theoretical and numerical modeling is developed based on the measured results for both autoclave processing and VaRTM (Vacuum-assisted Resin Transfer Molding) processing.


Experimental Micromechanics of Composites - In-situ Microscopic Damage Observation and Modeling

New types of composites are tested including carbon nanotube (CNT) polymer composites, ceramic fiber/matrix composites, and high-temperature polyimide matrix composites. Theoretical and numerical modeling is established based on the observed failure process in order to provide necessary feedback data for material design.
