“…39 On the other hand, the airframe of any flying vehicle comprises structural members that join by riveted lap joints. 40 It can be said that during riveting process, the structural members are subjected to punch loading. Since the incorporation of GNPs had a positive influence on the behavior of FML panels under punching test, it is recommended to add the GNPs into the composite laminate of FML.…”

The current study investigated the influence of incorporation of graphene nanoplatelets (GNPs) on quasi-static behavior of composite and fiber metal laminate (FML) panels. The unmodified and modified composite specimens and FML panels with 2/1 configuration were fabricated using a hand lay-up method and investigated through a quasi-static punch and indentation testing. The two sets of tests were conducted with a flat-ended indenter and the loading conditions were the same for all samples, except support spans which were varied. Following experimental testing, possible damages at the punch region were closely investigated and localized and global damages were observed. The results revealed that adding 0.2 wt% GNPs improved the strength and fracture toughness of specimens by delaying the failure modes. On the contrary, GNPs made the bonding between the aluminum and composite interface to weaken.

“…Various studies have reported on the mechanical properties of FMLs. [ 18–24 ] On contrary, the works related to the mechanical properties of FMLs with nanofillers is very limited. Zhang et al [ 25 ] investigated the influence of multi‐walled carbon nanotubes (MWCNTs) on the flexural and impact performance of GLARE with 3/2 configuration.…”

The present study investigates the effect of halloysite clay nanotubes (HCNT S) on the mechanical properties of glass reinforced aluminum laminate (GLARE) as a very popular fiber metal laminate (FML). GLARE (3/2) with quasi-isotropic lay-up, [Al/[(0 /90)/(45 /−45)]s/Al/[(0 /90)/(45 /−45)]s/Al], filled with different wt% ofHCNTs (0, 0.25, 0.5, 1, 2, and 3 wt%) were fabricated using hand lay-up followed by compression molding. Tensile, flexural, and impact properties of the fabricated GLAREs were evaluated. The failure of the specimens was examined using field emissionscanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDX) and visual inspection. Test results demonstrated that the incorporation of HCNTs improves the mechanical properties of GLARE. Among the studied wt%, the inclusion of 1 wt% of HCNTs to GLARE leads to maximum improvements of 35.67%, 8.50%, 28.85%, 50.47%, 50.27%, 30.43%, and 51.52% in tensile strength, tensile strain, Young's modulus, modulus of toughness, flexural strength, flexural strain, and impact strength, respectively, was attained by adding 1 wt% of HCNTs to GLARE compared to pristine GLARE. Meanwhile, increasing HCNT S content to 3 wt% reverse the trend. FESEM showed that, HCNT S are well dispersed in epoxy. However, a higher weight fraction of HCNT S in epoxy, that is, 3 wt% leads little agglomerations.

<div class="section abstract"><div class="htmlview paragraph">The study investigates the optimization of design parameters of riveted joints such as diameter of rivet, edge distance, and the amount of nanoclay filler in the modified GLARE laminate single lap riveted joints under pull-through test. Taguchi’s L9 orthogonal array was used to plan the experiments. The failure mechanism of riveted joints was observed to be elongation of rivet hole, followed by stress concentration, crack initiation, propagation in the interface, coalition of multiple cracks leading to delamination in the laminate. The failure of joint finally occurred by rivet pin fracture. The regression equations were developed for both failure load and maximum displacements with prominent level of confidence and the reliability of the equations were confirmed by experiments. The effect of individual and interaction of factors was evaluated using analysis of variance (ANOVA). The grey relational analysis (GRA) was conducted to determine the optimum combination of factors and levels. The GRA predicted the combination of factors and levels as “A3 (Diameter of rivet – 6.4 mm) -B3 (Edge distance – 35 mm) -C3 (Nanoclay wt.% - 5).”</div></div>
