Northrop Grumman is accelerating the development of high-temperature materials with its Scalable Carbon/Carbon Composite Robotic Additive Manufacturing (SCRAM C/C) to support emerging hypersonic and high-velocity weapons.

“We are pioneering a rapid manufacturing process that requires no tooling to fabricate aerospace-grade continuous fiber integrated composite structures,” said Dan Olson, vice president and general manager of Weapon Systems for Northrop Grumman. . “This advancement in manufacturing will deliver capabilities to the field much faster than traditional methods and ensure our warfighters have the latest technology and advanced weaponry to counter existing and future threats.”

SCRAM is a true industrial 3D printer reinforced with continuous fibers with 6 axes, which allows the manufacture of integrated composite structures. These structures then undergo a proprietary manufacturing process and are formed into C/C to serve the high-temperature materials community where intricate, netting-like shapes are required.

Historically, C/C manufacturing techniques have been labor intensive. By introducing process automation, manufacturing time and cost can be reduced by up to 50% compared to traditional methods, allowing faster access to capabilities in the field. Process automation has also shown a measurable improvement in component quality and consistency.

Northrop Grumman is printing continuous fiber composites at scale, an unprecedented achievement in the additive manufacturing industry. The company’s process does not require long-term tooling and incorporates in-situ consolidation of the composite, which significantly changes the cost paradigm for manufacturing high-temperature composites. The company has obtained several patents on SCRAM technology.
