“…Such connections should be watertight, sufficiently resistant to failure, and, modular panel assembly should be used to make composite-to-metal connection possible. A few different approaches to solving the problem have been presented recently [2,3]. Another group of problems is created by the connection between composite panels and supporting steel frames [5].…”

The paper presents a view on selected problems concerning application of steel sandwich panels to marine structures. Such problems connected with specificity of thin-skin laserwelded structure are varying in topics beginning from micro-scale properties of laser-welded T-joint through the joining of sandwich structures together up to connection and integration of such structures with a classical single-skin structure.

“…The use of structural adhesives in this type of joints instead of using the traditional systems will provide, amongst other advantages, less weight, more uniform tension distribution, water-proofing and elimination of the galvanic corrosion [5]. For this reason, studies have been carried out assessing the technical performance of adhesive joints between composite material and aluminium [6] or provide an analytical and experimental model to estimate the resistance of the adhesive joint when the composite material and the steel are joined together [7,8].…”

The composite materials of the polymeric matrix reinforced with carbon fibre have an extensive industrial application as they provide light and resistant structures. However, in many products (automobiles, aircraft, etc.), the composite materials must be joined to other components manufactured with aluminium alloys. The use of structural adhesive to bond these materials may be a good alternative if a specific design of the adhesive joint is carried out by maximising its performance and reducing its limitations. In the current work, the end-notched flexure (ENF) fracture test is used to assess the mechanical behaviour of the adhesive joint to facilitate the choice of the best adhesive and surface treatment of the adherends. However, in industrial applications of a great technical requirement (where the safety of staff or property may be at risk), the former experimental results are not enough and must be complemented with methods that can provide additional guarantee for a suitable reliability. For this purpose, a statistic analysis of the obtained experimental data has been carried out by means of the application of a Weibull distribution, in order to propose the adhesive and surface treatment that best combines the mechanical performance and high reliability. At the end, we can conclude that the epoxy adhesive with sand-blasting treatment for the aluminium and the peel ply for the carbon fibre has the greatest reliability (more than 90% for loads until 900 N).

“…The impact response of a range of novel sandwich structures based on fiber‐reinforced thermoplastic and fiber‐metal skin was investigated [15]. Boyd et al [16] studied the optimization of structural steel/composite connection for structural marine applications using genetic algorithms with parametric variation. The joint was the connection between steel hull and composite superstructure of naval vessel.…”

A study on the anchoring orientations of foam and sandwich composites with metal

Metallic anchors are used as the load transfer components for foam and sandwich composites when they are used as structural elements in design applications. The traditional method of fixation of these components is by gluing and fastening. The anchors are in the form of inserts and are imbedded in the foam during the foaming process. In this study, flexural testing was conducted on different metal anchor/foam configurations to establish typical interaction trends. The load‐deflection response, mode of failure, and fracture stresses of the structures were elucidated. Tests were conducted on foam and sandwich composites having rectangular, cylindrical, and taper geometries with different lengths. Leaf inserts were designed, manufactured, and tested inside foam and sandwich composites. Comparisons between the taper and leaf inserts are presented. Leaf inserts had better results compared with taper inserts in terms of adhesion and failure stresses. Finite element analysis (FEA) of the interactions between the inserts and the foam and sandwich composites under different loads was carried out. The FEA modeling results were very similar to the experimental results, thus validating the model. Simulations were also run with foam and sandwich composites with closeout configuration. Foam–sandwich with inserts had better adhesion and load‐bearing properties compared with same structures with closeouts. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers
