영어 초록

In efforts to characterize and understand the properties and processing of phenylethynyl-terminated
imide (LaRC PETI-5, simply referred to as PETI-5) oligomers and polymers as
a high-temperature sizing material for carbon fiber-reinforced polymer matrix composites,
PETI-5 imidization and thermal curing behaviors have been extensively investigated based
on the phenylethynyl end-group reaction. These studies are reviewed here. In addition, the
use of PETI-5 to enhance interfacial adhesion between carbon fibers and a bismaleimide
(BMI) matrix, as well as the dynamic mechanical properties of carbon/BMI composites,
are discussed. Reports on the thermal expansion behavior of intercalated graphite flake, and
the effects of exfoliated graphite nanoplatelets (xGnP) on the properties of PETI-5 matrix
composites are also reviewed. The dynamic mechanical and thermal properties and the electrical
resistivity of xGnP/PETI-5 composites are characterized. The effect of liquid rubber
amine-terminated poly(butadiene-co-acrylonitrile) (ATBN)-coated xGnP particles incorporated
into epoxy resin on the toughness of xGnP/epoxy composites is examined in terms of
its impact on Izod strength. This paper provides an extensive overview from fundamental
studies on PETI-5 and xGnP, as well as applied studies on relevant composite materials.
