Hossain et al. [33] have performed flexure tests on the GRPC, 0.1–0.4 wt%
CNF-filled GRPC showed up to 49% and 31% increase in the flexural strength
and modulus, respectively, when it is compared with the conventional one by
increasing loading of CNFs up to 0.2 wt% and the quasistatic compression proper-
ties. SEM evaluation has been revealed relatively with less damage in the tested
fracture surfaces of the nanophased composites in terms of matrix failure, fiber
breakage, matrix-fiber debonding, and delamination, when it is compared with
the conventional one.
Faguaga et al. [34] have studied the effect of water absorption on the dynamic
mechanical properties of composites, that are used for windmill blades. They have
found that the nanoclay-incorporated unsaturated polyester matrix system shows a
