Aerospace control surface with integral components

With ten patents and more pending, Ducommun’s Foam Matrix Core System™ (FMC) technologies are a unique and innovative set of technologies for producing net molded structures without the need for multi-piece assemblies. The Ducommun FMC system approach results in lofted composite parts that are lightweight and also low in cost. This proven technology has been flying on the C-17 since 2004, and has been employed in other programs such as JASSM, UCAV, UAVs, military ground vehicles and landing craft.

Where Ducommun Foam Matrix Core System technologies fit

The system is ideally suited for aerostructures like wings, winglets, control surfaces, fairings, blades, doors, antennas, missile bodies, integrated assemblies and similar contoured parts.

Many composite structures don't take full advantage of the unique design possibilities that these materials allow. The use of traditional configurations of skins fastened to ribs and stringers, or complicated assemblies using many pieces of machined core have a high part count and may require a number of unique manufacturing steps to complete the part.

Highly integrated structures using the various Ducommun’s FMC System™ technologies replace the large number of individual parts used in 'traditional' aircraft manufacturing with a single component that satisfies the requirements. Component price and lead times are further reduced by the use of a common set of commercial, off-the-shelf materials. Using Ducommun’s FMC System technologies we can incorporate mechanical and electrical components directly into the structure without additional tools or parts, resulting in reduced parts counts and labor costs.

Different Ducommun FMC System processes

In addition to systems used to create foam core based aerostructures, the Ducommun FMC System technologies also include AirCor™ systems and MatrixShield™ armor.AirCor systems produce strong, lightweight hollow structures for such applications as fuel tanks with integral parts and fittings. MatrixShield armor is an armor technology that provides molded-to-shape direct replacement parts that protect against threats while minimizing weight.
