U.S. Army awards Rowan University $14.5M to produce cold spray additive production


Rowan University, New Jersey has received $14.5 million from the U.S. Military Investigate Laboratory (ARL) to produce cold spray additive producing certification (CSAM). In a task titled “Advancing Structural Elements for Army Modernization Priorities by using Direct-Produce Approaches” Rowan scientists will implement technological advancements to boost the basic safety of troopers.

The undertaking groups Rowan College with world wide provider of paints, coatings and specialty elements PPG, Drexel University, Northeastern College, and the College of Massachusetts Amherst to create new products and techniques to procedure them.

Cold-spray additive production certification (CSAM)

Cold-spray additive production certification will involve the acceleration of metallic particles with a high-velocity supersonic fuel jet, bonding powdered products upon impact with obtaining surfaces or substrates. A lot quicker than the pace of audio, the particle velocity of cold spray enables fast get rid of and adhesion of polymers. This effects in a rapid and productive creation of large general performance composite components or fix of parts. 

“Additionally, this novel manufacturing methodology is a layer-by layer output of composites, which ought to decrease void and flaw content material,” defined John La Scala, affiliate chief the ARL’s Products and Manufacturing Sciences Division. “This should really make improvements to strength and longevity drastically, thus opening the prospective of applying this manufacturing strategy to prepare composites for extreme situations, though changing the present-day pricey production techniques with a substantially far more affordable methodology,”

Principal purposes of the know-how involve creating coatings or fixing equipment. The technological know-how has been utilised by engineers to maintenance motor gearboxes and make electrical motors. A commercialized chilly spray device is now offered in the type of SPEE3D’s LightSPEE3D 3D printer. Other industrial vendors of chilly spray-based mostly AM involve Influence Improvements, Hermle, and Titomic.

New CSAM Investigation Lab in Rowan

In the Chilly-Spray Additive Production certification Research Lab at Rowan’s South Jersey Technologies Park (SJTP), Dr. Joe Stanzione, associate professor of chemical engineering, will get the job done with the team of Dr. Francis (Mac) Haas, assistant professor of mechanical engineering. “We’re making a components science ecosystem here at Rowan,” Dr Haas stated. The lab will also convey together publish-doctoral scientists, doctoral learners, learn students and two dozen undergraduate students. 

The team’s work will focus on the manufacture and maintenance of polymer composites. “The significant particle velocity of cold spray enables fast heal and adhesion of polymers. This need to result in rapidly and efficient generation of high performance composite pieces or fix of sections,” added La Scala. Starting off with the ubiquitous polystyrene, the team will later move on to much more sophisticated composite supplies and devices as designated by the Military.

Materials developed through the study program may well be utilized for producing military devices much better and lighter, soldiers much more agile and motor vehicles extra sturdy. There is also potent opportunity for twin-use spinoffs into commercialized sectors these as civil aviation, cars, wellness treatment and house exploration.

“We will perform to make materials more promptly, to make them improved and simpler to repair service offsite and, importantly, onsite in the field,” Dr Stanzione mentioned. “That incorporates every thing from elements for tanks and jeeps, to usable instruments, and helmets.”
