The demand for higher fuel efficiency and low fuel pollution rates leads to the development of lightweight hybrid structures. The predominant aim is to develop innovative light products with extreme versatility with bionomic and economic balance. Lightweight materials in the structures have successfully solved these problems in many industries, especially automobiles and aerospace. There is an emerging scope in producing automotive components by joining Al and Mg-based alloys with materials such as thermoplastics, ceramics and fibre-reinforced composites. Developing hybrid structures by employing metal–polymer joining is still a significant challenge. There are as many joining techniques available for joining metal with a polymer. Owing to certain drawbacks, some methods are ineffective, such as high processing time for adhesive bonding and mechanical fastening due to increased weight. The friction-based welding technique benefits hybrid joining due to its low heat-affected zone with less metallurgical damages. The study provides an overview of many emerging technologies for joining aluminium to thermoplastic/carbon fibre-reinforced polymer for lightweight structures. The paper compares different joint configurations and the effect of process variables on the microstructural and mechanical properties of hybrid joints. In addition, attempts are made to comprehend contemporary developments in the finite element simulation studies of hybrid structures. The paper also highlights recently developed strategies and gaps in areas where future studies might be focussed. Thus, the paper gives an overview of the advancements and relevance of the emerging joining technique for aluminium to polymers/carbon fibre-reinforced polymer hybrid structures.

“…Adhesive bonding quality is related to surface treatment and the choice of bonding agent, but the large number of users of bonding agents will pollute the environment. To overcome the above shortcoming, laser welding [9][10][11][12][13], induction welding [14][15][16][17], friction stir welding [18][19][20], and ultrasonic welding [21][22][23] were adopted in joining of CFRTP to Al alloy. Among all the joining technologies employed to date, laser welding with high e ciency and few defects was more useful to expand the application range of multi-materials structures.…”

Laser surface texturing is generally a promising approach to enhance the adhesion property of metalthermoplastic hybrid structure, and the effect is related to the groove con guration. Laser joining of carbon ber reinforced thermoplastic composite (CFRTP) to 6061 Al alloy under various groove con guration was carried out, aimed to investigate the effect of groove width and depth on interfacial morphology, mechanical properties and fracture behavior of CFRTP/ Al joints. The tensile-shear force was tested, and the fracture surface and interface morphology were observed by scanning electron microscopy. Besides, the numerical simulation of temperature eld was conducted to reveal the joining mechanism. The results indicate that the tensile shear strength of CFRTP/ Al joint gradually increases with the increase of groove width and reaches the peak value of 22.8 MPa when the width is 0.5 mm, then it decreases as the groove width is further increased. Compared to groove width, the tensile shear strength of CFRTP/ Al joint presents similar variation trend with the increasing groove depth on Al alloy surface. When the groove depth reaches 0.6 mm, the maximum joint strength is 24.33MPa. After laser textured Al alloy, the surface fracture mode of CFRTP/Al laser joint features mixed fracture mode including cohesive fracture and interface fracture. This study provides a deeper understanding of the effect of groove con guration on the laser joining of CFRTP/ Al hybrid structure and potentially lays a foundation for the adjustment of suitable groove con guration toward obtaining the desired effect.
