“…There are several joining methods [58] used for composite materials, as shown in Figure 1. For assembling the large composite structures, the conventional methods which are used in industries are mechanical fastening using rivets and bolts, co-consolidation bonding, and chemical bonding by control adhesives [59]. Mechanical fastening methods, namely bolting, riveting and fasteners, are the most common method of joining in industries.…”

The ultrasonic welding (UW) technique is an ultra-fast joining process, and it is used to join thermoplastic composite structures, and provides an excellent bonding strength. It is more cost-efficient as opposed to the conventional adhesive, mechanical and other joining methods. This review paper presents the detailed progress made by the scientific and research community to date in the direction of the UW of thermoplastic composites. The focus of this paper is to review the recent development of the ultrasonic welding technique for thermoplastic composites to thermoplastic composites, and to dissimilar materials. Different ultrasonic welding modes and their processing parameters, namely, weld time, weld pressure, amplitude, type of energy directors (EDs) affecting the welding quality and the advantages and disadvantages of UW over other bonding techniques, are summarized. The current state of the ultrasonic welding of thermoplastic composites and their future perspectives are also deliberated.

“…A commercial thermoplastic PA6 based CFRP supplied by Celanese (Celstran® CFR-TP PA6 CF60-03) with a continuous unidirectional (UD) fibre tow and a thickness of 0.13mm[9], was used as the reinforcement patch. This was bonded to the steel substrate with a thermoplastic adhesive multilayer-film Nolax Cox 490-1 (Nolax) from the Nolax AG [10]. The material properties provided by the supplier are given in Table 1.…”

Carbon Fibre Reinforced Metal Hybrid (CFRMH) materials that combine a sheet metal substrate with a reinforcing carbon fibre patch represent a promising solution to reduce weight while increasing the structural and crash performance of future automotive vehicles. CFRMHs cannot be formed with conventional stamping processes and at high volumes. This currently reduces their widespread application. Roll forming is increasingly used in the automobile industry for the forming of lightweight and high-strength metal structural components. The major deformation mode in roll forming is simple bending and this reduces interlaminar shear and compressive stresses that lead to fibre failure and delamination issues when stamping CFRMH sheet materials. This work analyses the potential of applying the conventional roll forming process for the manufacture of a simple top hat section shape from CFRMH sheet. For this, first, the material is produced in a hot press and then formed to shape in a laboratory roll forming facility at room temperature. Different layup sequences are tested, and component quality is analysed after roll forming by visual inspection. The results suggest that roll forming presents a promising manufacturing method for the production of automotive components from CFRMH sheets. The roll formed open shells are joined to produce crash box structure and tested in 3-point bending. The results show that depending on the fibre orientation a significant increase in weight specific strength is achieved.

“…[20][21][22] However, recent attempts have been made to use high-performance thermoplastic-based adhesives, which offer low cost and rapid production potential. [23][24][25][26][27] In this context, the use of recyclable elium resin as an adhesive that does not require high curing temperatures is seen as a potential breakthrough for the production of reparable and/or non-permanent joints. In this study, the use of recyclable elium thermoplastic adhesives, which could be a good alternative to traditional epoxy thermoset adhesives, was investigated as a bonding component in composite structures.…”

The preference for thermoplastic composites over thermoset ones is steadily growing, especially in constructing resilient, lightweight, and fuel‐efficient structures in industrial settings due to their recyclability and superior energy absorption. Elium®, an acrylic‐based thermoplastic resin, offers enhanced stiffness and improved toughness at room temperature. Investigation into elium‐based composites with diverse fiber reinforcements has revealed elium's potential as an alternative to traditional thermoset epoxy resins. This study explores recyclable elium resin as an adhesive for creating curable and non‐permanent joints in various elium‐based composites. Various joining techniques, including adhesive bonding, mechanical joints, and hybrid bolted/bonded connections, were assessed, with hybrid bonded/bolted (HBB) joints emerging as a preferred solution for structures requiring higher load‐carrying capacity. The study's results indicate that, when using elium adhesive, elium‐hybrid bolted/bonded (HBB) joints demonstrate superior mechanical strength compared to their epoxy counterparts, resulting in improved toughness and stiffness values for each type of composite material. In addition, the research demonstrates superior load‐bearing strengths in bonded glass/elium composite joints using elium adhesive compared to bolted joints, with HBB joints featuring elium adhesive displaying even higher load‐bearing strengths. This research highlights the potential of elium‐based composites and adhesives in various industrial applications, enabling the production of lightweight, robust structures with exceptional damage tolerance.Highlights Investigates recyclable elium resin for curable and non‐permanent joints. Elium‐based composites offer lightweight, robust, and damage‐tolerant structures. Elium HBB joints demonstrate superior strength. FTIR analysis reveals distinct chemical signatures and bonding characteristics. Elium adhesive enhances bond strength.
