Studying roughness parameters and the topography of stiffening ribs in composite sandwich structures is important for understanding these materials’ surface quality and mechanical properties. The roughness parameters describe the micro-geometry of the surface, including the average height deviation, roughness depth, and waviness. The topography of the surface refers to the spatial arrangement and distribution of features such as bumps, ridges, and valleys. The study investigated the roughness parameters under three scenarios based on two SPIF process parameters: tool rotational speed(N) and feed rate (f). The vertical step was held constant at 0.4 mm across all scenarios. In scenario A, the process parameters were set at f = 300 mm/min and n = 300 rpm; in scenario B, f = 1500 mm/min and n = 3000 rpm; and in scenario C, f = 1500 mm/min and n = 300 rpm. The experimental research topography analyses revealed that the surface roughness of the stiffened ribs was highly dependent on the SPIF process parameters. The highest feed rate and tool rotational speed produced the smoothest surface texture with the lowest maximum height (Sz) value. In contrast, the lowest feed rate and tool rotational speed resulted in a rougher surface texture with a higher maximum height (Sz) value. Furthermore, the contour plots generated from the topography analyses provided a good visual representation of the surface texture and roughness, allowing for a more comprehensive analysis of the SPIF process parameters. This study emphasizes optimizing the SPIF process parameters to achieve the desired surface quality and texture of stiffened ribs formed in Litecor® panel sheets.

“…ThyssenKrupp Steel Europe's LITECOR® composite material began to appear in several studies, including weldability by resistance spot welding [11], mechanical joining based on the mortise-tenon joint [12], and relying on three-stage joining to produce a more significant and stiffer mechanically locked joint [13]. Furthermore, studies expanded to investigate whether a commercial sandwich material can fill the role of automotive and industrial applications [14,15]. Regarding components crafted from steel-polymer sandwich composites, Hoffmann [16] demonstrated that they achieve nearly identical weight reductions compared to those composed entirely of aluminum (with only a 10% increase in weight), yet at a considerably reduced cost (at least 30% more economical).…”

Advances in sandwich composites have given rise to materials that amalgamate the elevated flexural stiffness and buckling resistance found in metals with the lightweight characteristics of polymers. These materials exhibit significant potential for use in contemporary lightweight structures, not solely due to the aforementioned attributes, but also owing to their effective provision of sound, vibration, and thermal protection. In the structures using sandwich materials, joining methods based on fusion welding, adhesive bonding or mechanical fastening are employed. Clinching is a manufacturing technique that mechanically joins two or more materials without the need for heat or additional components. This method relies on achieving high plastic deformation to establish a secure bond. The research deals with the possibility of using the clinching method for joining metal/polymer/metal composite sheets in combination with high-strength steel and micro-alloyed hot-dip galvanised steel sheets. The clinching method with a rigid die proves unsuitable for joining the examined combinations of sandwich material with steel sheets.

“…In addition to the technology of joining, it is extremely important to master the technology of shaping new materials. The authors of the work [ 25 ] conducted a series of tests to determine the tribological properties of the LITECOR ® composite under consideration. The aim of these studies was to determine the value of the friction coefficient under various friction conditions.…”
