Joining technology adhesive bonding

In the area of the cohesive joining technologies, the use of adhesive bonding is an attractive method for connecting different joining parts. Adhesive bonding s total potential is not fully realized yet, especially in the interfaces between textiles and electronic components.

The composites sector offers multiple benefits for adhesives manufacturers. As various materials interface, traditional joining technologies aren t always sufficient imder the required performance extremes, writes Dow Automotive Systems Frank Billotto in this issue. Adhesives, however, are being formulated to accommodate the bonding of these diverse, dissimilar substrates..Read Next-Generation Composite Adhesives on pp. 15-16 to learn more. 

The materials being joined are often referred to as the adherends or substrates. The properties of the composite made when two adherends are united by adhesive are a function of the bonding, the materials involved and their interaction by stress patterns. It can be appreciated that adhesive bonding technology presents some very unfamiliar concepts to all engineers and, in particular, to civil engineers. 

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 critical parts in commercial and military aircraft and helicopters, spacecraft, rockets, missiles and the US Space Shuttle. The American Primary Adhesively Bonded Structure Technology (PABST) Programme, which ran from 1976-81, was an imaginative attempt to advance significantly the use of bonded... 

This chapter reviews such beneficial techniques for joining technologies as embroidery and adhesive bonding. Finally, it addresses the problem of smart textile infrastructure development by building a multi-layer structure. 

The application of adhesives in early aircraft manufacturing was not very different from the general evolution of this joining technology. For example, variations in the stability of wooden constructions against moisture due to less suitable adhesives such as casein were experienced. However, impressive parts like the wooden wing of the pre-World War II Fokker F-36 airliner (33 m wing span) were bonded with no in-service problems reported. 

The principal advantage of adhesives is in the ability to reduce stress concentration in joints by transferring load via the whole of the bonded area, as opposed to the discrete load points introduced by bolts or spot welds. In addition, the low density of adhesives imparted by their polymeric nature makes their use in joining technology attractive to the designers of weight-efficient structures and their uptake has therefore been widespread within the aerospace industry.
