Metal Additive Manufacturing

Additive manufacturing (AM) – the process of building up solid layers of material to form a finished solid part — is an emerging and exciting technical discipline. Also referred to as “3D printing,” many...

Lightweight composite structures offer significant long-term cost-saving opportunities for the U.S. Army as replacements for traditional metal structures....

In order to address issues related to mechanical and vibrational stresses that are commonly experienced in mounting, launch,...

Reinforcing polymers with strong/stiff fibers is nothing new. Such materials have been used pretty much since aircraft were first created. In those pioneering days, wings were reinforced with woven...

Metal additive manufacturing (3D printing), also known as Direct Metal Laser Sintering (DMLS) or Powder Bed Fusion (PBF), is changing the way metal parts are designed and produced. New software,...

Researchers from the U.S. Army Research Laboratory and Arizona State University (ASU) have designed a super-strong alloy of copper and tantalum that can withstand...

DETECTING PLASTIC LANDMINES

Hidden PFM-1 anti-personnel landmines are unexploded ordnance (UXO) devices that pose a difficult challenge to conventional...

Aircraft corrosion is a multi-faceted issue that requires more than a simple, one-dimensional approach. To enable Air Force Research Laboratory (AFRL) personnel to...

The wax-filled thermostatic element was invented in 1936 by Sergius Vernet (1899-1968). Its principal application was in automotive thermostats used in the engine cooling system....

Electropolishing has become a common metal finishing process used in the aerospace industry to help improve the overall quality of metal components. These components...

It’s common, especially in the aerospace industry, for parts that are fracture critical to be Liquid Penetrant Inspected (LPI) prior to installation. Also known as Dye Penetrant...

In August 2017, Qantas Airlines laid down the challenge to both Boeing and Airbus to offer an aircraft that can cross one of aviation's “last frontiers.” That “last frontier” was an...

The objective of this research was to hydraulically pressurize the internal diameter of one 102mm Polymer Matrix Composite (PMC) over-wrapped cylinder up to 25,000 pounds per...

Purdue University researchers have developed a superstrong material that may change some manufacturing processes for the aerospace and automobile industries.

Laser diodes and laser diode arrays (LDAs) are widely used throughout military systems, for sighting and range finding, but also at high power levels as offensive and defensive...

After extensive review from the US Army Research Laboratory (ARL) Electrical Safety Office, it was...

Additive manufacturing was invented more than 30 years ago and, from small beginnings in prototyping, has developed and grown into a $6 billion industry. While additive...

Nett Warrior

Nett Warrior is the US Army's next generation US integrated soldier system that replaces Land Warrior. It is designed to be an integrated dismounted situational awareness and mission command system for use during combat...

Content addressable memory (CAM) is one of the most promising hardware solutions for high-speed data searching and...

The development of transition metal-based molecules and materials that can be switched between low-spin and high-spin...

Resistive Random Access Memory (RRAM) devices have drawn much interest in the last decade,...

Metric-Sized Metal Shapes

Parker Steel Company (Maumee, OH) offers metric-sized metals suitable for applications where presized metric parts are needed....

Through NASA’s Convergent Aeronautics Solutions (CAS) Project, a team of engineers working within its Spanwise Adaptive Wing (SAW) project is investigating the feasibility of bending or shaping...

In aerospace applications of materials, increasing strength often leads to a decrease in ductility. Engineers have developed a Super Steel that addresses this strength-ductility tradeoff. In...

A soldier heads back to camp, grabs a power bar and unloads his gear. The power bar, which was "printed" minutes earlier, contains all the nutrients his body currently needs, according to...

Researchers at ETH Zurich have developed a lattice structure capable of absorbing a wide range of vibrations while also being useful as a load-bearing component in propellers, rotors, and...
