“…Once the rotating rivet is inserted into the polymer-based component whose thermal conductivity is low, the local temperature increases at the rivet tip and causes the rivet tip to expand locally, forming an anchor inside the polymer-based component, as depicted in Figure 9. Friction riveting is suitable to connect polymer or polymer composites to different metals for a variety of applications in aerospace, automobile, and civil engineering [84]. The process was invented and patented at the Helmholtz-Zentrum Geesthacht [85].…”

Multi-materials of metal-polymer and metal-composite hybrid structures (MMHSs) are highly demanded in several fields including land, air and sea transportation, infrastructure construction, and healthcare. The adoption of MMHSs in transportation industries represents a pivotal opportunity to reduce the product’s weight without compromising structural performance. This enables a dramatic reduction in fuel consumption for vehicles driven by internal combustion engines as well as an increase in fuel efficiency for electric vehicles. The main challenge for manufacturing MMHSs lies in the lack of robust joining solutions. Conventional joining processes, e.g., mechanical fastening and adhesive bonding involve several issues. Several emerging technologies have been developed for MMHSs’ manufacturing. Different from recently published review articles where the focus is only on specific categories of joining processes, this review is aimed at providing a broader and systematic view of the emerging opportunities for hybrid thin-walled structure manufacturing. The present review paper discusses the main limitations of conventional joining processes and describes the joining mechanisms, the main differences, advantages, and limitations of new joining processes. Three reference clusters were identified: fast mechanical joining processes, thermomechanical interlocking processes, and thermomechanical joining processes. This new classification is aimed at providing a compass to better orient within the broad horizon of new joining processes for MMHSs with an outlook for future trends.

“…Andréa et al [28] explored the impact resistance of AA2024-T3 alloy and carbon fiber reinforced polyphenylene (CFRP) sulfide joints using the low-velocity drop-weight impact tests at impact energies of 2 J to 8 J, and found that 6.5 J is the critical absorbed impact energy of the joints. Borba et al [29,30] explored the impact damage and damage propagation sensitivity of CF-PEEK frictional riveted joints and bolted joints. Zhang et al [31] studied the energy absorption characteristics of CFRP plates with different fiber modulus under different impact angles, and found that the intra-laminar force behavior shows nonlinear relationships between impact angle and fiber modulus.…”

The low-velocity impact behaviors of DP590/AA6061 self-piercing riveting (SPR) joints are studied at the impact energies of 5 J, 10 J, 20 J, 30 J, and room temperature (25℃). The lap shear and fatigue tests, and the cross-sectional microscopies of joints are used to assess the mechanical property evolutions of the joints after low-velocity impact. The results show that the absorbed impact energies of SPR joints reach the critical value at an impact energy of 30 J, the exceeded impact energy causes crack failures in the sheets and decreases the interlocking performance of the joints. The static property and the absorbed energy of the SPR joints are reduced by 16% and 36% when the joints are impacted at 30 J, respectively. The low-velocity impacts do not change the failure forms of the joints, but significantly reduce the mechanical interlocking properties of the joints. The fatigue lives of the SPR joints are reduced due to low-velocity impact, and the impacted joints are more sensitive to cyclic loadings.

“…Developed and patented by Helmholtz-Zentrum Geesthacht [1], this joining process consists of a rotating cylindrical metallic rivet being pressed against overlapping polymeric components, generating heat by friction and creating metallic insert spot joints. Polymers with and without fiber reinforcements and both thermoplastics and thermosets have been successfully joined [2][3][4][5].…”

“…Thus, simplifications and assumptions must be made. Considering the number of works and investigations into new possible applications and material combinations using friction riveting process [5,9], it is of great importance that the understanding of the process also be developed from a computational modeling stand point.…”

Thermomechanical modeling of the metallic rivet in friction riveting of amorphous thermoplastics

The present work aims for an initial computational simulation with finite element analysis of the friction riveting process. Knowledge and experimental data from friction riveting of AA2024-T351 and polyetherimide supported the computational simulation. Friction riveting is a friction-based joining technology capable of connecting multiple dissimilar overlapping materials in a fast and simple manner. In this paper, the plastic deformation of the metallic rivet, process heat input, and temperature distribution were modeled and simulated. The plastic deformation of the metallic rivet is of key importance in creating the mechanical interlocking and main joining mechanism between the parts, being this the focus of this work. The influence of the polymeric material was considered a dynamic boundary condition via heat input and pressure profiles applied to the rivet. The heat input, mainly generated by viscous dissipation within the molten polymer, was analytically estimated. Three experimental conditions were simulated. The heat flux values applied in modeling of the different conditions were determined (8.2, 9.1, and 10.2 W/mm2). These yielded distinct plastic deformations characterized by a diameter of the rivet tip, from the initial 5 mm to 6.2, 7.0, and 9.3 mm. The maximum temperatures were 365, 395, and 438 °C, respectively.
