Automated Fiber Replacement

Composite materials, as compared to many traditional manufacturing materials, offer weight reduction, greater strength to weight ratio, greater design flexibility, and superior performance in a corrosive environment.

Automated fiber placement is a process that applies resin pre-impregnated fibers on complex tooling surfaces. The fiber comes in the form of what is referred to as 鈥渢ows鈥�. A tow is a bundle of fibers and is approximately 0.125鈥� wide by 0.005鈥� thick.  The tows are fed to a compaction roller and heated on the FPM head, and through CNC programmable robotic movements are placed in courses across a tool surface.

NCAM has two Ingersoll FPMs that are used in the manufacture of complex-shaped structure. Both machines are located within an environmentally controlled enclosure.
