Spoilers in bonding area

Ducommun has many different capabilities that allow it to build complex bonded assemblies that may include machined metal parts, complex cores, and composite or metal skins. In addition to fabrication, Ducommun has complete in-house engineering, testing and tool design capabilities to support bonded assemblies. Our experience in bonded structures spans many decades and includes parts on military and commercial aircraft.

There are times when a bonded structure shouldn't be a bonded structure. Many assemblies can benefit from our innovative Foam Matrix Core System™ processes. An important element of these patented technologies is design-for-integration. The FMC System™ results in lower part count and fewer manufacturing labor hours. When compared to conventional designs such as a bolted or secondarily bonded wing, for example, a FMC System design relies on structural foam cores that provide integrity and support primary load path among

integral fiber reinforced components. Fewer parts and the elimination of secondary bonding or mechanical fastening results in fewer touch labor hours as well as fewer subcomponent parts to manufacture and inventory.
