The Society for the Advancement of Material and Process Engineering (SAMPE) annual conference is currently in process in Baltimore, MD. So far there have been a few highly informative conference sessions. In the exhibit hall, there seems to be a fair amount of foreign companies in attendance. Overall, the general feeling observed is that the start of 2009 was extremely slow for composite processing, however in the last few months material orders have increased. There is an increased sense of optimism for the use of composites in wind energy, defense, infrastructure, and even aerospace. Many of which composite sandwich panels will play a role.

A furniture manufacturer in Dubai is looking for quotes for composite sandwich panels. The panels need to be thin, (.7-1.2mm thickness), and need to have a foam core. In addition, the core needs to be an elastic material such as polypropylene. Skins can be carbon, fiberglass, or aluminum.

Annual demand is expected to be between 3,000-4,000 square meters.

In the building of large composite structures, such as the new the new aircraft by Airbus and Boeing, the use of computer modeling is playing an increasingly important role. The same is true in the design of composite sandwich structures used where weight, specifications, and cost are important.

By using what is called, “Finite Element Analysis”, or FEA, engineers can model a composite sandwich structure, and closely predict loads and failure points prior to actually constructing a panel. The engineer can vary skin and core material in the design, and vary lay-ups and ply schedules of the composite face sheets.

Doing this often elements the “guess and check” method of using composites for a product. Optimization allows the composite sandwich structure to meet all required levels of compression and shear stregth, while eleminiting any excess materials. This helps reduce weight, which is often the reason in selecting composites in the first place. Additionally, when weight is reduced and less material is used, costs go down, and this is important for everyone.

Here is a link to a recent NASA Tech Brief.

Popular FEA software used in composites include:

DRS Technologies has been awarded a $16.2 million dollar contract to supply Multi-Temperature Refrigeration Container System (MTRCS) units to the U.S. Army’s Natick Soldier Systems Center at Natick, Massachusetts.

It is a pretty good guess that these containers, which carry medical supplies and blood, will be built with composite sandwich panels.
