Authors: Gaurav Pandey, Erik T Thostenson, Dirk Heider
OBJECTIVES
Design self-sensing composite systems.
Terminology
• CNT: Carbo nanotubes
• TDR: Time domain reflectometry
Composite systems evaluated:
• CNT based syntactic foams
• CNT sheet based CFRP laminates
• Embedded wire based CFRP laminates with TDR sensing
CNT based syntactic foams
• Lightweight.
• Sense damage and strain
CNT sheet based CFRP composites
• One step manufacturing process using pre-preg rolls.
• Sense damage and strain
CFRP laminate with embedded TDR sensor
• 2-D tracking of impact location
• Repairable sensor system
