Resumen:
Epoxidized soybean oil (ESO) was proved to be a good
alternative to partially replace a synthetic commercial
epoxy resin in a formulation to obtain thermosetting
polymer, contributing to transform a vegetable oil into
a higher added value product. This work focuses on
the study of the fracture behavior of copolymers based
on anhydride-cured epoxy systems with different contents
of ESO as a replacement for the synthetic resin.
It was found that fracture toughness was greatly
improved when replacing diglycidyl ether of bisphenol
A (DGEBA) by ESO, being the critical stress intensity
factor (KIC) 1.067 MPam1/2 for cured ESO and 0.557
MPam1/2 for cured DGEBA. The better performance of
ESO networks was ascribed to its higher ability to
attain plastic deformation. Moreover, for DGEBA-ESO
systems, the morphologies generated during the curing
process were also considered to account for the
observed results.
