This work aimed to investigate the effect of two factors in two levels including
graphene nano-platelests (GnPs) at 1 and 2 wt.% and post curing temperature
(PCT) at 140 and 150°C on the flexural properties including strength and
modulus of epoxy/ carboxylated nitrile butadiene rubber (XNBR) composites.
Nanocomposites were made manually using of a mechanical stirrer. Threepoint bending tests were performed in room temperature to evaluate the
flexural properties of the samples. Further, scanning electron microscope
(SEM) was used to observe the fracture surfaces of them. The results showed
that the presence of GnPs in epoxy/XNBR composites increased flexural
modulus while an increase in PCT did not have much effect on the flexural
modulus. Also it was found that adding 1 wt.% GnPs and PCT of 140°C
improved the flexural strength of the composite.
