The use of bonding in the shipbuilding industry extends to yacht, charter and military applications. In yacht construction, bonding has become an indispensable Figure 8.12 An insulated rail joint with screws (right) and additionally adhesively bonded (left) at —28°C.

While for locomotives, bonding is used almost exclusively to fix protective foils, it also offers a wide field of applications in tramways, regional traffic or long-distance transport. The head-end of the German ICE, for example, is a bonded integral plastics construction. The windows are fitted by bonding, as are the sidewalls, ceilings, floorings and equipment […]

In modern vehicle construction, high priority is given to weight reduction, improved long-term mechanical strength and corrosion resistance, increased comfort, crash resistance and higher body rigidity. Intelligent lightweight constructions can only be obtained by consistently using a material mix of steel, light metal and plastics which may be joined by conventional thermal and mechanical joining […]

Automobile construction is subdivided into the manufacture of passenger cars, trucks, buses and motor homes. In the future, weight reduction will become increasingly important both in passenger car construction and industrial vehicle construction, although this may not be gathered from the development which has taken place in the past, in particular in passenger car construction. […]

Bonding technology as a high-performance joining technique for extremely long-life and heavy-duty structures was developed in aircraft manufacture, where it proved to be a success despite some critical periods during development. This technology clearly contributed to improvements in aircraft structures, and will continue to be essential in aircraft manufacture, notably when fiber-reinforced plastics are taken […]

In aircraft manufacture, the labor-intensive production process involves very inten­sive quality control measures. To start with, the personnel must be highly qualified, and every step performed to produce adhesive joints must be documented. Extensive measures are also taken during product incoming inspection, especially in the case of the primers and adhesives; after which every production […]

In modern aircraft manufacture, the bonding process starts with a chemical surface preparation of the components to be joined (see above). On completion of the final back-washing step, the surfaces are dried and then coated (as immediately as possible) with an anticorrosive primer, either by spray application or by using an electrostatic coating process. Before […]

At present, when manufacturing metallic aircraft the most widely used surface preparation method is a combination of cleaning, pickling and anodizing (as described above). Usually, the raw aluminum parts are precleaned with organic solvents, followed by alkali degreasing, pickling in diluted hydrofluoric acid in order to remove accumulations of copper on the surfaces and staining […]

As mentioned previously, in structural aircraft manufacture, phenolic resin adhe­sives are used which may today be applied in the form ofprefabricated, supported or unsupported films. Furthermore, epoxy resin film systems supported with fabrics or mats are used which are processed on anticorrosive primers (also described previ­ously). In order to obtain plastication, the epoxy resin matrices […]

Bonding is a surface-to-surface and material joining technique that makes it possible to join any combination of similar or dissimilar materials. In aircraft manufacture, bonding offers the following benefits compared to riveting, joining by screws, soldering and welding: • High aerodynamic surface quality of the bonded components owing to smooth, high-precision contours. • Excellent properties […]
