It is necessity to understand the degradation of the
polymer to produce high-quality and high-performance polymeric products in the
development of polymeric materials. In this study, we aim to find out the cause
of the strain and defects by terahertz (THz) imaging measurements of the polymer
composite material with non-destructive and non-contact. In addition, we try to
make the depth profile of the interaction and dispersion between the components
in the polymer composite material, resin flow, and residual stress, at the same
time we aim to get the information of the three-dimensional distribution of
these behaviors.
Application for evaluation of the structure and physical
property of polymer materials by using THz imaging spectroscopy is the first in
the world. There has never been such a non-destructive measurement to link the
micro- and macroscopic molecular structure changes (intermolecular interactions
and strain degradation). Thus, it is expected to greatly contribute to improving
physical properties and new material development for the polymer material which
is required recently more various properties and functions with understanding
the mechanism of the physical properties expression.
