Nanographene inclusion effect on the mechanical and low velocity impact response of glass/basalt reinforced epoxy hybrid nanocomposites

Abstract

In the present study, hybrid glass/basalt fiber composites containing nanographene (GnP) were manufactured for investigation of low velocity impact properties at the impact energy of 30 J. Also, their flexural and tensile properties were experimentally characterized. During the experiments, both laminate configurations as basalt and glass at outer and inner skins were treated for impact and mechanical tests. Failure mechanisms were analyzed with taking photographs over the front and rear sides of the samples and SEM observations on the impacted region after the impact tests. Results from this study indicated that incorporation of GnP at 0.1 wt% revealed a significant improvement in impact and mechanical properties indicating the better load transfer between GnP-matrix resin-fiber interactions.

Hybrid Epoxy Composites with Both Powder and Fiber Filler: A Review of Mechanical and Thermomechanical Properties

“…For composites that were modified with 0.1 wt.% GNPs, the highest mechanical values, such as tensile strength, flexural strength, and impact resistance were obtained. Likewise, Erklig and Dogan introduced nanographene to hybrid epoxy composites (0.1; 0.25; 0.5 wt.%) reinforced with woven S-glass fabrics and basalt fabric [93]. Figure 5 presents the manufacturing method of the composites.…”

Buckling analysis of graphene nanoplatelets‐doped carbon/aramid hybrid polymer composite plates

“…[56] Another significant result is that the composite samples containing GNPs show lower elongation than the pure epoxy sample, which is resulted from the higher flexural rigidity of the nanoparticle-doped composite laminates. [31,34,57] Figure 5B compares the average critical buckling loads obtained from the lateral load-displacement curves of the composite samples. From these data, we can see that the GNPs addition resulted in the enhancement of the critical buckling loads of the carbon/aramid reinforced composite.…”

“…It is now well established from a variety of studies, that the thermal, electrical, and mechanical properties of a composite material may be enhanced significantly by incorporating micro/nanoscale particles in a polymer matrix. [30][31][32][33][34][35][36] Carbon-based nanomaterials have recently great attention due to their extraordinary mechanical, thermal, and electrical properties. [37][38][39] These carbon-based nanomaterials are formed by the different dimensional arrangements of carbon atoms such as C60 in 0D, carbon nanotubes (CNTs) in 1D, graphene nanoplatelets (GNPs) in 2D, and nano-carbon aerogels in 3D.…”
