Resumo
In aerospace industry, Carbon nanofibers (CNFs) Pyrograf III have been investigated
for the manufacture of nanocomposites. CNFs have excellent physical and chemical
properties with low cost production however the functionalization of the surface is
necessary to enhance the dispersion and tailor CNF to the host polymer. To this end,
CNF surface was functionalized with acrylic acid (AA) via ionizing radiation process
with objective to introduce functional groups on its surface, which may promote good
interface between CNF and epoxy resin system. Nanocomposites were manufactured
by two different methodologies of CNF dispersion in epoxy system. Three roll milling
methodology promoted better dispersion due to the powerful shearing forces.
Nanocmoposites manufactured with CNF functionalized with AA 20wt% solution via
gamma irradiation presented better mechanical property as well as highest fiber matrix
contact angle.
