“…One of the progressive ways of developing this approach is a wider use of polymer composite and adhesive coatings [6,7]. The use of adhesively bonded steel and patches in typical ship applications are described and the factors governing patch design, methods of surface preparation to ensure good bond durability in a marine environment, and choice of adhesives are discussed [8]. Results from published and unpublished Glasgow Marine Technology Centre (GMTC) research describe important aspects of structural adhesives.…”

A new adhesive material and a restoration technology for marine equipment units are proposed. The optimal content of hardeners of different nature is found, and the effect of temperature conditions used for crosslinking epoxy resin DER-331, on the adhesive properties of the polymeric material is determined. The polymerization of the epoxy oligomer DER-331 and polyethylene polyamine (PEPA) hardener at a temperature T = 413 ± 2 K is found to enhance the adhesive properties of the polymeric material by 3.2–3.6 times, as compared to polymer GEN-150. In addition, the separation pattern of metal surfaces was analyzed, which allowed for an in-depth evaluation of the adhesive strength at separation and its variation upon increasing the content of hardeners introduced. Based on complex studies, it is shown that the developed polymeric adhesive should be used in the restoration of marine transport units, in particular, wheel fit in the compressor section of turbocharger.

The aim of this paper is to assess the performance of two types of bonded joint with reference to specific design concepts, materials and application for hybrid steel-composite panel construction. The joints are (a) laminate-to-frame connections and (b) butt joints between adjacent laminates. The objectives are (a) to understand the structural behaviour, (b) to determine the failure mechanisms and (c) to determine the effect of the joint geometry on the strength of the bonded joints. The materials used for these joints were polyester-glass composite laminates, mild steel sections and epoxy adhesives. The paper describes the results from mechanical testing and numerical analyses for these joints. A key conclusion is that structural epoxy adhesives provide substantial joint strength to composite panels even though the composite uses low-strength resin. The joint strength is governed by adherend geometry.

Untersuchung des Prozesses zum Unterwasserkleben von Halterungssystemen

Betrieb und Wartung von Wasserbauwerken und ‐fahrzeugen erfordern häufig die nachträgliche Montage von Ausrüstungsgegenständen, wie Sensoren, Sonarsender oder Korrosionsschutzequipment unter Wasser. Durch Schweißen und oder mechanisches Fügen entstehen metallurgische/mechanische Kerben, weshalb im abgeschlossenen IGF‐Projekt „Unterwasserkleben“ ein geklebtes Haltersystem grundlegend entwickelt wurde. Ziel des Vorhabens „Unterwasserklebprozess“ ist die Untersuchung des Einflusses der Prozessparameter des mehrstufigen Injektionsprozesses (Medien, Zeiten, Drücke, etc.) auf die Verbindungsgüte und die Entwicklung eines entsprechenden teilautomatisierten Werkzeugs für den Einsatz durch Taucher oder ferngesteuerte Systeme. Investigation of the process of underwater bonding of holder systems. Operation and maintenance of waterway structures and vehicles often requires the subsequent installation of equipment such as sensors, sonar transmitters or corrosion protection equipment under water. Welding and or mechanical joining creates metallurgical/mechanical notches, which is why a glued holder system was fundamentally developed in the completed IGF project “Underwater Bonding”. The intent of the project “Underwater Bonding Process” is to investigate the influence of the process parameters of the multi‐stage injection process (media, times, pressures, etc.) on the bonding quality and the development of a corresponding semi‐automated tool for use by divers or remote operated vehicles.
