Closing remarks

Much pioneering research work has been completed in the science and technology of adhesion and adhesives. A lot of that work has been directed to solving problems for technically demanding bonding applications, and the resultant understanding has enabled further development and technology transfer. Whilst the substrates to be bonded, the adhesives used, the operating conditions […]

Relevance to civil engineering

We have seen that structural adhesive bonding has been employed in the aerospace and other industries for several years, whereas its use in civil engineering is relatively recent. Adhesive bonding can present some very unfamiliar concepts to many engineers and, in particular, civil engineers and this may partially explain the extremely cautious embrace of the […]

Vehicle and automotive

Adhesives have been employed in the automotive industry since its earliest beginnings, with the use of natural resins to bond wood and fabric bodies. With the advent of the all-steel monocoque adhesives disappeared from the body, although they continued to be used for interior trim applications and are still used in this role today. The […]

Railway

Adhesives are used in a civil engineering context, in the track, and for the construction of rolling stock. Taking these applications in order, heavily filled acrylic adhesives have been used to provide a longitudinal shear connection between adjacent precast concrete beams in bridge structures. Although in the final deck mechanical devices aid the adhesive, bonding […]

Marine and offshore

Casein and then formaldehyde resin compositions have been used as adhesives and gap fillers in wooden boat construction for many years. The most significant use of resorcinol-formaldehyde resins was for the construction of wooden minesweepers for the Royal Navy, each vessel requiring some 3 to 5 tonnes — used mostly for laminating the hull. Polyester […]

Civil engineering

Many of the comments about the use of adhesives in building apply equally to civil engineering. The section on Historical Development outlined some of the uses of natural adhesives, for joining wood or Fig. 1.4.

Building

The majority of the adhesive used in the construction industry is concerned with fastening decorative finishing materials to the insides of buildings. For instance, the attachment of ceramic tiles and mosaics to floors and walls, wooden and flexible floor coverings, ceiling tiles, thermal insulation materials, wall veneers, covings, nosings, and so on, accounts for the […]

Aerospace

It has often been observed that the application of adhesives to metal fabrication, in common with many other technological innovations, was pioneered by the aircraft industry. It is ironic that this industry, in which safety and reliability command paramount attention, should lead the departure from traditional methods of joining. Today adhesives are used to bond […]

Engineering applications of adhesives

It is clearly impossible to identify and to document all of the applications of adhesives in engineering assembly and fabrication. Many uses are, anyway, either of a relatively trivial nature or else do not place great demands on the adhesive material. The following sections review some of the major applications of adhesives in several different […]

Historical development

Sticking things together is a common enough task, and materials exhibiting adhesive properties have been employed in a sophisticated manner since earliest times. Natural adhesives such as starch, animal glues and plant resins have been used for centuries, and are still used widely today for packaging and for joining wood. Rubber — based adhesives were […]
