Testing Military Vehicle Steering Systems

Military vehicles play a vital role in protecting our society — and inevitably encounter many extreme conditions across their lifespan. From the varying weight, to the rough terrain, there is a lot that can go wrong. Military steering systems must therefore be engineered to take on such extremes. This begins at the design stage and ends with analysis through testing. It's here the parts are tested to their limits and validated against the original specification and real-life requirements.

Evaluation of Peel Ply Surface Preparation of Composite Surfaces for Secondary Bonding

Lightweight composite structures offer significant long-term cost-saving opportunities for the U.S. Army as replacements for traditional metal structures. However, high-strength economical bonding processes must be developed to join composites in order for them to be viable replacements. The Army is exploring approaches, also under evaluation in the commercial aerospace industry, to reduce the process steps associated with composite bonding.

Enhanced Contacts for Inverted Metamorphic Multi-Junction Solar Cells Using Carbon Nanotube Metal Matrix Composites

In order to address issues related to mechanical and vibrational stresses that are commonly experienced in mounting, launch, and deployment of spacecraft, metal matrix composite (MMC) electrodes were fabricated with carbon nanotubes (CNTs) as reinforcement. The research plans were centered on first developing and selecting appropriate processes for fabricating CNT-MMCs based on characterization of their material properties, followed by optimizing MMC designs based on electrical testing under stress. Efforts in the program were also directed toward implementing the CNT-MMCs into solar cell device processing in a process compatible with standard clean room procedures.

Fiber-Reinforced Thermoplastic Composites

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 cotton, or silk fabric skins, impregnated with nitrocellulose ‘dope’ to seal against the wind, and laminated wood was reinforced with fabric bonded with adhesive. Although there have been a myriad of developments along the way from those early days to where we are now in the 21st century, the principles of reinforcement are much the same.

Round TFT LCD Displays

Data Image (Winter Park, FL) has announced new round TFT LCD color displays in two sizes: 3" and 4.2" in diameter. They can be used as digital avionics, power meters, speedometers, rpm gauges, temperature indicators, strain gauges, volt/current meters or a simple clock. The display can show a single gauge or display multiple parameters. The formats for the displays are 432 × 432 for the 3" and 720 × 720 for the 4.2". Both have a brightness of 1000 nits typical and wide viewing angles thanks to the IPS glass technology used on both versions. Both have wide temperature rating. They are available with or without capacitive touch panels for user interface.

Reusable Rapid Prototyped Blunt-Impact Simulator

Rapid prototyping (RP) is the term most commonly used to describe additive manufacturing technologies. An additive manufacturing technology is any manufacturing process that fabricates a part by adding one layer of material at a time, one on top of the other, to produce detailed 3-D geometries directly from 3-D computer-aided design (CAD) models.

Lightweighting Parts Using 3D Metal Printing

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, processes and materials are redefining manufacturing value equations for specific types of parts, which can lead to improvements on existing products, new business models and new markets.
