In this study, effects of addition of carbon nanotubes (CNTs) and graphene
platelets (GPLs) on characteristics of carbon/basalt fiber reinforced intra-ply
hybrid composites were investigated. The composites were fabricated using
vacuum assisted resin infusion molding (VARIM) method in two types including
bare and 0.1, 0.5 wt.% of GPL and CNT nanoparticles filled hybrid composites.
Fabricated normal and multiscale composites were cut by water jet and
mechanical properties of specimens were examined by tensile, flexural, SBS
experiments. Therefore, the modulus of elasticity, flexural modulus, tensile
and flexural strength and ILSS of bare and multiscale composites were compared.
Thermomechanical properties of fabricated composites were evaluated
by dynamic mechanic analyze (DMA), thermogravimetric analyze (TGA) and
thermal conductivity (TC) tests and storage modulus, loss modulus, damping
ratio, glass transition temperature, weight loss and derivative weight loss were
compared in fabricated normal and multiscale composites. Similarly, modal
properties of fabricated composites such as natural frequency and damping
factor were obtained by vibrational tests and compared in fabricated composites.
According to the results, the addition of carbon-based nanoparticles
improved the characteristics of carbon/basalt fiber intra-ply hybrid composites.
The response of composites was directly proportional to the addition ratio of
the carbon-based nanoparticles.
