5. 내 용 :
Time Domain Reflectometry (TDR) is a method of sending a fast pulse to a
transmission line, and then monitoring the reflection signal returning back
from impedance changes along the line. It can interrogate distributed
changes along the entire length of the sensor line, rather than at discrete
points as with a fiber optic sensor. Thus, TDR can be used as a distributed
sensor to monitor in real time both process parameters during composite
manufacturing processes and health parameters of composite structures in
service. The presentation will show a few examples of TDR applications 1)
to monitor resin flow and degree of cure in vacuum assisted resin transfer
molding (VARTM) processes and 2) to monitor crack propagation,
distributed strains and failure locations for a few test samples under
various load conditions.
