Abstract. Sandwich composite is a special form of a laminated composite comprising a combination of different materials that are bonded to each other so as to utilize the properties of each separate component to the structural advantage of the whole assembly. Usually a sandwich structure consists of two relatively thin, stiff and strong faces separated by a relatively thick lightweight core, for instance, honeycomb, balsa or foam cores. The purpose of sandwich structure is to achieve a stiff and simultaneously light component. A natural fiber composite also plays a vital role in automotive and construction filed due to their bio degradable behaviour and ease of manufacturing. This paper reviews sandwich structures, various tests performed on it and their properties along with some studies of mechanical behaviour of natural fiber composites. Major applications of the sandwich specimens are also highlighted in this work.

“…Sandwich composites are extensively used in high‐performance structural applications especially aerospace, automobiles, high‐speed trains, and marine industries 1–3 . Nowadays, in aerospace industries, metals are increasingly being replaced by composites, as they are lightweight and exhibit high impact resistance, good thermal insulation, and better fatigue performance 4,5 .…”

In this study, the fire‐retardant performance of lightweight sandwich composites, with modified epoxy impregnated carbon and glass fabric reinforcements and an aluminum honeycomb core, is investigated. The fire‐retardant performance of the fabricated sandwich composites is improved by treating carbon fiber reinforcements with phosphoric acid, and by impregnating the epoxy matrix with different loadings of ammonium polyphosphate (APP) fire‐retardant additive. The laboratory aging behavior of sandwich composites is also carried out to further investigate the degradation resistance of the panels under extreme conditions. Fire and mechanical properties of epoxy and sandwich panels are investigated using UL‐94, limiting oxygen index (LOI), thermal gravimetric analysis, compression tests, and three‐point bending tests. In the case of sandwich composites, a maximum of 1345 and 45.2 MPa flexural and compression modulus, respectively, are achieved with 10 wt% APP content in epoxy. Maximum 30% and 33% LOI values are achieved with 10% APP content in the epoxy and sandwich panels, respectively.

“…Improving the grammage of core and surface layer to enhance honeycomb bearing strength will consume a lot of base materials. Therefore, many other improved explorations have been carried out in many references, such as filling material in honeycomb cells, double‐core paper of honeycomb core structure, honeycomb structure with grid, cell structure with hexagonal and quadrilateral combination design, square honeycomb structure, combination of corrugated and trapezoidal honeycomb, honeycomb structure with variable thickness, single‐walled channel improved core structure, etc. According to the performance characteristics and technological requirements of paper materials, the abovementioned structures can be used less for paper materials.…”

Honeycomb paperboard's out‐of‐plane bearing performance is one of the important properties in packaging field application. Further improvement of its bearing performance has important value in engineering practice. In this paper, a honeycomb core structure was designed, and the bonding dimension and manufacturing process were designed. The mechanism of out‐of‐plane quasi‐static compression deformation of reinforced honeycomb paperboard was analyzed by experiments. The theoretical model of out‐of‐plane platform stress was constructed by applying the plastic deformation, plastic energy dissipation and energy conservation theory. The results show that the improved structure can be mechanically bonded in a flat state with less technological changes. Under the same honeycomb core material and core size parameters, the bearing strength of the improved structure increases by an average of 3.9 times to conventional structure. In order to meet the same compressive strength requirement, the improved structure can reduce the performance requirements of honeycomb core material or increase the core size compared with the conventional structure. When the honeycomb core cell is larger, the tension on the core layer required for the production process is reduced. The theoretical and experimental data are in good agreement with each other, and the relative errors are all less than 13%.
