The technology isn’t a new one though. For years composites or sandwich panels have been used in the manufacture of both civilian and military aircraft and more recently used in racing vehicles, ship building and even specialized architecture. A typical Boeing civil airliner may be comprised of up to 5-15

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

% composite panel, although recently Boeing announced that the new 7E7 would be composed of up to 50% composite, making it ultra light weight while maintaining optimum durability.

The success of composite technology in the aviation field has made it attractive to other industries seeking to apply the ben

At present, composite technology can be applied to body panels and accessories, f
