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.”

Nathan Strout After landing a contract with the U.S. Air Force in April, California-based company Labelbox announced May 20 it is making its artificial intelligence training data platform available more widely to the federal government and intelligence community. Labelbox offers a software platform by the same name that allows development teams to manage the data used to train machine learning algorithms. For instance, in order for a machine learning tool to successfully begin identifying missile launchers in satellite imagery, it needs to be fed hundreds — or even millions — of pre-labeled pictures identifying the objects it needs to identify. The more accurate training data is fed to the algorithm, the better it works. Some government machine learning projects need to process petabytes of data per day, the company says, a flow of data that can be overwhelming. “Labelbox is an integrated solution for data science teams to not only create the training data but also to manage it in one place,” said CEO Manu Sharma in a statement. “It's the foundational infrastructure for customers to build their machine learning pipeline.” The platform can be used in the cloud or on-premises, allowing data science teams to work together across agencies or locations, the company claims. In April, the company announced it had won an Air Force Innovation Hub Network (AFWERX) Phase 1 Small Business Innovation Research contract to conduct feasibility studies on how their platform could integrate with ongoing Air Force efforts. Now, the company is partnering with Carahsoft Technology Corp. to make their platform more widely available to the federal government and the intelligence community. Carahsoft will be able to provide the platform to interested agencies through its NASA Solutions for enterprise-wide procurement contracts and reseller partners, the company announced May 20. https://www.c4isrnet.com/artificial-intelligence/2020/05/20/this-platform-will-help-train-ai-algorithms-for-the-military/

Tony Osborne | Aerospace Daily & Defense Report LONDON—Industry in Denmark, Israel, Italy, the Netherlands, Norway, and the UK have secured component repair work for the F-35 Joint Strike Fighter. Work assignments for the maintenance, repair and overhaul work on some 400 repairable items including avionics, life support systems, landing gear, pumps and power systems for the aircraft was issued by the F-35 Joint Program Office (JPO) on Feb. 12. Under current plans, the F-35 enterprise is awarding contracts for more than 770 repairable items on the aircraft. The first batch of 65 of these contracts was issued in late 2016 for so-called high-value electrical components, fuel, mechanical and hydraulic systems, and ejection seats. Having secured the lion's share of the first round of contracts, British industry has also grabbed a significant proportion of work in the second, British government officials have confirmed. This will lead to the creation of additional jobs at Sealand Support Services Limited (SSSL), the joint venture established between BAE Systems Northrop Grummanand the Defense Electronics and Components Agency (DECA). It will carry out the component repair work at its facility in Sealand, Wales, to support European operators of the aircraft.
