Surface treatments for bonded repair of metals,dependent upon the stability and bondability of the adherend surface . Combinations of heat moisture and stress have been shown to be particularly effective in sorting out or discrimination between various surface preparations used in the prebond conditioning or treatment of both aluminum and titanium alloys.

The Power of Transformational Ideasnificance than it would have been for some perfect laboratory test coupon. The bond flaws simply did not grow, which gives great confidence in the reliability of adhesively bonded structures. Even the slow-cycle testing under extreme environments and loads did not damage the bonds in test coupons.

Repair of composite aircraft,composites in structural applications where reduced structural weight leads to significant fuel savings. Many secondary structural components including flaps, fairings, and floor panels have been constructed from graphite and kevlar based composites. Figure 7.1 shows the use of composites in two recent aircraft .

Crack patching: experimental studies, practical applications,lic aircraft components. This approach, known in Australia as crack-patching, pioneered by Aeronautical Research Laboratories since about 1972, has been successfully used to repair Royal Australian Air Force aircraft, including Hercules, Mirage and F111, suffering from cracking due to fatigue or to stress-corrosion.
