AIRCRAFT MANUFACTURE

The development of flight over the last six decades is pretty impressive. Today we jet all over the earth as if it were the most natural thing in the world. However, no less impressive is the development of adhesives during the same period. Over the years, this practical household helper has become a high-tech tool.

The specific reasons for this include the fact that bonds have lifetimes of up to 30 years, high resistance to dynamic loads and media and resistance to extreme, and sometimes very rapid, temperature changes, from sub-zero temperatures in the stratosphere to ground-level temperatures in desert climates.

One advantage of the adhesive elements in paste form is obvious. Because of its consistency, it can also be used locally and its compensatory tolerances allow for a stable bond. Also, it offers high stability because the use of adhesives allows the structure to remain intact during the binding process. This offers the chance for new composite materials to be developed.

Weight reduction is an economically advantageous aspect, in addition to the technical advantages offered by adhesives.

Every pound that is saved reduces the operating costs of an aircraft; and savings in the production costs and — based on the overall life of the vehicle extremely important for the auto and aviation industry. The application of bonding technology in aircraft manufacture allows extremely lightweight design due to the consequent use of light metal alloys, fiber-reinforced plastics and so-called sandwich components. Bonding is used for internal struc­tures for manufacturing structures with lightweight honeycomb sheets.
