US and Japanese Scientists Conduct Joint Composites Study

Dr. Keisuke Umezawa of the Air Systems Research Center in the Japanese Ministry of Defense (JMoD) recently joined the Air Force Research Laboratory on an engineers and scientists exchange program (ESEP). The JMoD chose Umezawa for the ESEP based on his experience as a stress analysist of polymer matrix composite materials. Also, Umezawa has been heavily involved in the development of the next generation Japanese fighter aircraft, including the development of the test program for prototype PMC structures.

NASA to Advance Unique 3D Printed Sensor Technology

Mahmooda Sultana recently won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and then transmitting that data via a wireless antenna — all from the same self-contained platform that measures just two-by-three-inches in size.

New Coating Repels Ice from Any Surface

Researchers used a new theory in physics called stress localization to create a durable silicone polymer coating capable of repelling ice from any surface. The new material uses elastic energy localization where ice meets the material, triggering cracks at the interface that slough off the ice.

NIF Experiments Support Warhead Life Extension

It was a normal morning for design physicist Madison Martin at Lawrence Livermore National Laboratory (LLNL). At 7:45 a.m., she settled into her classified workstation with a cup of tea to check the results of a numerical calculation she ran overnight. If the calculations proved correct, the experiment she was designing on the National Ignition Facility (NIF) would deliver the data her colleagues needed to verify that a refurbished nuclear warhead would perform as expected.

Discovery Could Lead to Munitions That Go Further, Much Faster

Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide. This discovery coincides with the one of the Army's modernization priorities: Long Range Precision Fires. This research could lead to enhanced energetic performance of metal powders as propellant/explosive ingredients in the Army's munitions.

Porous and Stiff Material for Aircraft Lightweighting

Researchers have developed and manufactured a family of architectures that maximizes the stiffness of porous, lightweight materials. 3D printing and other additive production techniques make it possible to manufacture materials with internal structures of previously unimaginable complexity. Achieving this requires that the internal structures be intelligently organized for maximum efficiency.

The stiffness in the material’s interior is achieved through plate-lattices rather than trusses. These structures that are up to three times stiffer than truss-lattices of the same weight and volume.
