Rowan University Project Will Develop Composite Materials Used to Protect Soldiers

By Kimberly Hoodin

Rowan University will lead a $14.5 million Department of Defense/Army Research Lab project to create new composite materials – and ways to process those materials – that will help modernize the Army and improve the safety of soldiers in the field.

The project, titled “Advancing Structural Materials for Army Modernization Priorities via Direct-Write Approaches,” will be led by researchers from Rowan University teamed with PPG, Drexel University, Northeastern University and the University of Massachusetts Amherst to create new advanced composite and plastic materials and ways to process them. The project is driven by a cooperative agreement with the U.S. Army Combat Capabilities Development Command Army Research Laboratory.

The team will work on developing innovative materials by using “cold-spray” advanced manufacturing technologies. The work will focus on polymers, starting with polystyrene, then move on to more advanced composite materials and systems, as designated by the Army.

“The high particle velocity of cold spray enables rapid cure and adhesion of polymers. This should result in the fast and efficient production of high-performance composite parts or repair of parts,” said John La Scala, associate chief the ARL's Materials and Manufacturing Sciences Division and cooperative agreement manager for the research program. “Additionally, this novel manufacturing methodology is a layer-by-layer production of composites, which should reduce void and flaw content. This should improve strength and durability significantly, thereby opening the potential of using this manufacturing technique to prepare composites for extreme conditions, while replacing the current expensive manufacturing methods with a much more economical methodology.”

Researchers hope to develop materials to be used for making military equipment stronger and lighter, soldiers more agile and vehicles more durable. Longer-term, the team sees the potential for use of the materials in the fields of civil aviation, automotive, health care and space exploration.

“We will work to make materials more quickly, to make them better and easier to repair offsite and, importantly, onsite in the field,” Dr. Joe Stanzione, associate professor of chemical engineering at Rowan University said. “That includes everything from parts for tanks and jeeps, to usable tools, and helmets.”

    Boeing’s Autonomous MQ-25 Completes First Test Flight with Aerial Refueling Store

    St. Louis, December. 9, 2020 – Boeing [NYSE: BA] and the U.S. Navy have for the first time flown the MQ-25 T1 test asset with an aerial refueling store (ARS), a significant milestone informing development of the unmanned aerial refueler. The successful 2.5-hour flight with the Cobham ARS – the same ARS currently used by F/A-18s for air-to-air refueling – was designed to test the aircraft's aerodynamics with the ARS mounted under the wing. The flight was conducted by Boeing test pilots operating from a ground control station at MidAmerica St. Louis Airport in Mascoutah, Ill. “Having a test asset flying with an ARS gets us one big step closer in our evaluation of how MQ-25 will fulfill its primary mission in the fleet – aerial refueling,” said Capt. Chad Reed, the U.S. Navy's Unmanned Carrier Aviation program manager. “T1 will continue to yield valuable early insights as we begin flying with F/A-18s and conduct deck handling testing aboard a carrier.” Future flights will continue to test the aerodynamics of the aircraft and the ARS at various points of the flight envelope, eventually progressing to extension and retraction of the hose and drogue used for refueling. “To see T1 fly with the hardware and software that makes MQ-25 an aerial refueler this early in the program is a visible reminder of the capability we're bringing to the carrier deck,” said Dave Bujold, Boeing's MQ-25 program director. “We're ensuring the ARS and the software operating it will be ready to help MQ-25 extend the range of the carrier air wing.” The Boeing-owned T1 test asset is a predecessor to the engineering development model aircraft being produced under a 2018 contract award. T1 is being used for early learning and discovery, laying the foundation for moving rapidly into development and test of the MQ-25. Following its first flight last year, T1 accumulated approximately 30 hours in the air before the planned modification to install the ARS. Earlier this year the Navy exercised an option for three additional MQ-25 air vehicles, bringing the total aircraft Boeing is initially producing to seven. The Navy intends to procure more than 70 aircraft, which will assume the tanking role currently performed by F/A-18s, allowing for better use of the combat strike fighters.
