“…The interfacial fracture toughness of the aramid fibre-enhanced adhesive joints was found to be significantly greater than the corresponding value measured for the baseline composite. In a comparable research study, Ning et al [28] integrated nano-fillers in the form of a vapour-grown carbon fibre (VGCF) interleaf with the filler concentration of 10 g/m 2 at the aluminium-carbon fibre composite to achieve more than 40 times enhancement in the initiation fracture toughness properties relative to the baseline composite without an interleaf. The same authors extended their research to investigate the effectiveness of the VGCF interleaf on the mode II fracture toughness of glass fibre-reinforced plastic (GFRP)/aluminium [19] and carbon fibre-reinforced polymer (CFRP)/aluminium [22] composites.…”

This paper presents a novel technique for improving aluminium–glass/epoxy composite interfacial bonding through the generation of metallic nano-architectures on the metal surface. Silver nanowires (AgNWs) deposited via solution casting at varying concentrations and annealed at different temperatures in an air atmosphere improved the aluminium-glass/epoxy composite fracture toughness as measured via mode I experiments. For AgNW concentrations of 1 and 3 g/m2 deposited via a single-stage process and annealed at 375 °C, the initiation fracture toughness of the aluminium-glass/epoxy composite improved by 86% and 157%, respectively, relative to the baseline composite without AgNWs. The corresponding steady-state fracture toughness of these nano-modified fibre metal laminates (FMLs) were at least seven times greater than the baseline composite. The FML variant in which AgNWs were deposited at a concentration of 3 g/m2 through a two-stage process followed by annealing at 375 °C and 300 °C, respectively after each deposition, achieved the highest steady-state fracture toughness of all nano-modified composites—a fracture toughness value that was 13 times greater than the baseline composite. Intrinsic and extrinsic toughening mechanisms dictated by the morphology of the silver nano-architectures were found to be responsible for the improved initiation and steady-state fracture toughness in nano-modified FMLs.

“…On the other hand, numerous studies have shown that nanofillers (nanoclays, carbon nanofiber, multi‐walled carbon nanotubes (MWCNTs), nanosilica, and graphene sheets) as additives enhance the interfacial bonding strength of hybrid composites . For instance, nanosized Al 2 O 3 particles introduced into an epoxy adhesive have been found to increase the adhesion strength of bonded steel dramatically .…”

“…The results affirmed that the CNTs were not well dispersed in the resin matrix, which affected the adhesive performance. Another study investigated the effects of VGCF (vapor grown carbon fiber) on mode‐I fracture interlaminar mechanical properties of aluminum/CFRP laminates . However, the major matrix in laminates is epoxy resins, and it is impossible to use them at temperature above 200°C.…”

Multi‐walled carbon nanotubes (MWCNTs) were introduced to improve the interfacial properties of titanium‐based fiber metal laminates, and the corresponding reinforcement mechanism and failure behavior were revealed. Diverse weight fractions (0, 2.5, 5, 7.5 wt%) of MWCNTs were dispersed in polymerized monomer reactant (PMR) polyimide adhesives by ultrasonic dispersion. Single lap shear tests of samples were conducted and average shear strengths were experimentally measured to characterize the interface bonding strengths between the titanium and polyimide. The shear strength of this polyimide adhesive was further enhanced by incorporating MWCNTs, with over 87.5% improvement for the MWCNTs toughened adhesive joints with concentration up to 5 wt%. Meanwhile, the influence of MWCNTs on the interlaminar shear strength (ILSS) of the Ti/Cf‐PMR polyimide was investigated through short‐beam three‐point‐bending tests. It was found that MWCNT incorporation into the polyimide significantly enhanced the ILSS by 39.4%. Furthermore, scanning electron microscopy (SEM) was used to investigate the interface morphology, and the results of SEM images revealed MWCNTs failure morphologies, such as pull‐out, fracture, and bridging. The above results indicated the contribution of MWCNTs to the improvement of shear strength in these fiber metal laminates. POLYM. COMPOS., 39:E1159–E1168, 2018. © 2017 Society of Plastics Engineers

“…Experimental results show the improvement on the interlaminar mechanical properties of Mode‐I fracture in terms of much higher critical load and fracture toughness. The combination of mechanical patterning with acid etching increase mechanical properties only for the case without nanofiller addition .…”

Effect of 3D‐woven glass fabric and nanoparticles incorporation on impact energy absorption of GLARE composites

et al. 2017

View full text Add to dashboard Cite

Proper combination of fiber reinforced composite and metal is a novel concept that it caused the advent of fiber‐metal laminates. This study reports the impact response of 3D‐woven glass fiber fabric composite cores experimentally, and it describes the effect of silica and graphene nanoparticles addition on energy absorption behavior of laminated fiber‐metal composites. The composites are manufactured by VARTM method with 71% fiber volume fraction. The low velocity impact tests are performed with drop‐weight impact test machine with various impact energies. The results show higher impact performance of plain‐weave samples compared with 3D‐woven glass fiber fabrics under different impact energies. The 3D‐woven glass fiber fabrics are preferred in case of using samples with lower weights. POLYM. COMPOS., 39:3528–3536, 2018. © 2017 Society of Plastics Engineers
