abstract = "Lightweight and highly conductive composite associated with good
impact and tribological properties could be used in the aerospace
industry to replace metal for an aircraft skin and still provide
effective shielding against electromagnetic interference (EMI).
Also, phenol-furfuryl alcohol resins (PFA) are excellent
candidates to replace existing thermoset matrices used for
obtaining glassy carbon, both in its pure form and reinforced with
nanoscale structures. The synthesis of PFA allow obtaining a resin
with better properties than that showed by conventional phenolic
resins and with synthesis and cure processes more controlled than
observed for the furfuryl alcohol resin. This work has as main
purpose the synthesis and thermal characterization of PFA resin
and its nanostructured composites with different concentrations of
carbon nanotubes (0, 0.1, 0.5 and 1.0 wt%). PFA resin was
synthesized with 1:2:1 molar ratio of phenol/formaldehyde/furfuryl
alcohol, according to the more appropriate condition obtained
previously. The specimens were evaluated by thermogravimetry (TGA)
to knowledge of the temperature of thermal degradation, either by
actual analyses as simulated by simulation heating rate conversion
software (known as Highway Simulation). The introduction of CNT in
PFA sample does not affect its thermal stability. The values of
residual weight found for samples with CNT additions are close to
the values of the phenolic resin in the literature (about 60%
residual weight).",
