Abstract
Abstract An experimental study is presented into the strengthening of composite T-shaped joints using carbon nanoparticles. The structural properties of carbon fibre reinforced epoxy composite T-joints containing a small weight fraction (1%) of carbon nanotubes (CNTs), carbon nanofibers (CNFs) or graphene nanoplatelets (GNPs) within the polymer matrix phase is studied. Experimental testing reveals that the strengthening effect depends on the nanoparticle type, with CNFs being the most effective at increasing the failure initiation load (~68%), ultimate failure load (46%) and absorbed energy capacity (~200%) of the T-joint. Improvements to the structural properties are also gained with the use of CNTs, although there is little or no gain with GNPs. The improvements to the T-joint properties correlate with the increases to the interlaminar fracture toughness properties of the carbon fibre reinforced composite laminates containing the nanoparticles. The strengthening and toughening mechanisms induced by the nanoparticles are described.

The highly cross-linked thermosetting polymers used as adhesives and as the matrices of fibre composites for the construction of lightweight vehicles are very brittle, and finding effective toughening solutions for such engineering applications is a long-standing problem. An anhydride-cured thermosetting epoxy polymer has been modified by the addition of different wt% of silica nanoparticles, core–shell rubber particles and hybrids with equal wt% of both. The fracture energy was measured at ambi...

Abstract Through-thickness reinforcements using z-pins is a highly effective method for increasing the delamination resistance of fibre-polymer laminates. Here we report a hierarchical approach of incoporating carbon nanofillers and z-pins to further improve delamination toughness. The nanofillers include one-dimensional (1D) carbon nanofillers (e.g. carbon nanotubes, carbon nanofibres) or two-dimensional (2D) nanofillers (i.e. graphene nanoplatelets). Results of the interlaminar fracture toughn...

Abstract Mechanical joint and adhesive bonding are two typical joining methods for composite materials. The bolt fastening method is reliable but increases the weight of the structure and cuts the composite fiber, which may cause stress concentration and strength degradation. The adhesive bonding method has a higher bonding strength than the mechanical fastening, but the bonding strength can deteriorate depending on the various parameters that influence the environmental conditions and manufactu...

Abstract Fibre composites with thermoset polymer matrices are widely used. However, thermosets are very brittle, which can limit the applications of fibre composites. In this work, silica nanoparticles (SNPs) were used to modify two fibre sizings to improve the toughness of carbon fibre composites. Mode I interlaminar fracture and fatigue crack growth tests were conducted on the composites made using the silica nanoparticle-sized fibres. There was no significant change in the fatigue crack growt...

Abstract Carbon nanomaterials secure promises of incorporating exceptional mechanical performance and multifunctional properties into polymers. However, questions concerning type of carbon nanofiller, fraction and corresponding change in relevant property are yet to be answered. In this study, graphene platelets (GnPs) and carbon nanotubes (CNTs) were added individually into epoxy adhesive and corresponding structure-property relations were investigated experimentally and numerically. The study ...

Abstract Out-of-plane joints, such as joints between T, I, Z, L and hat (omega) stiffeners and skin panels are essential part of composite structures. To ensure the integrity of these assemblies, the inclusion of a filler material in the junction region between the skin, flanges and web is necessary. The conventional filler is a rolled unidirectional fibre bundle or resin filling, but there are many other proposed methods in the literature. This paper reviews the state-of-the-art work available ...

Abstract null null Fused deposition modelling (FDM) is an additive manufacturing process for the 3D printing of continuous fibre-thermoplastic composite laminates. The electrical conductivity of continuous carbon fibre (CF)-nylon filaments and laminates printed with a Markforged MarkTwo® FDM machine is experimentally investigated. The axial electrical conductivity of single filaments measured before, during and following the FDM process reveal a large reduction (∼40%) due mostly to breakage of c...

The connection problem of composite tubular members in the domain of transmission ducts and assembly structures remains an obstacle to the wide application of continuous fibre-reinforced composites. Traditional longitudinal connection techniques of composite tubular members to address this problem mostly require the use of metal connectors, which reduces the weight reduction effect of composite materials to a certain extent. To explore a new solution, a cylindrical laminated tube component with ...

Abstract A laser technology has been developed for fabricating structures from composite layers based on biopolymers: albumin, collagen, and chitosan with single-walled carbon nanotubes (SWCNT). The structures are intended for cardiovascular devices and tissue-engineered implants. This is evidenced by the results of studies. The composite layers were fabricated due to the phase transition of biopolymers and SWCNT aqueous dispersion under the influence of laser pulses. At the same time branched 3...
