Plastic Bearings Have Staying Power

Plastic bearings are strong enough to outperform and outlast metal in countless applications, however, they are often not considered a viable choice in the engineering community due to the common misconception that plastic is inferior or weaker compared metal. Uncover common misconceptions and learn the true reliability of tribologically-optimized plastic bearings in this whitepaper from the motion plastic experts.

Electropolishing Prepares/Pre-Cleans Parts Properly Prior To Penetrant Testing

It is 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 Inspection (DPI) or simply Penetrant Testing (PT), this method is used to detect micro-cracks or other defects that could serve as an initiation site for failure. In order to properly execute a penetrant test, the surface of a metal part must be thoroughly clean of any debris, smeared metal, or any amorphous layer that may be hiding a hairline crack thus yielding a false reading.

Customized Masking Solutions Don’t Require Customized Masks

If you’re masking with conventional methods, you know the challenges associated with complex design configurations and need for reliable protection from aggressive chemical processes, high-temperature coatings, or surface treatment processes. Even minute gaps or voids in coverage can result in edge-lift and leakage that can significantly compromise protection and adversely impact your bottom line.

Method for Exfoliation of Hexagonal Boron Nitride

Langley Research Center, Hampton, Virginia NASA’s Langley Research Center has developed a method for exfoliating commercially available hexagonal Boron Nitride (hBN) into nanosheets a few atomic layers thick. Currently, hBN has limited use because it is insoluble with limited dispersibility, despite hBN having excellent thermal conductivity and electrical insulation. Langley’s novel method provides for exfoliated hBN nanosheets that are soluble or suspendable in a variety of solvents, allowing for their bulk preparation and incorporation into composites, coatings, and films.

Sucrose-Treated Carbon Nanotube and Graphene Yarns and Sheets

Applications include structural materials for aerospace vehicles, space habitats, and lightweight but mechanically robust consumer devices. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center has developed a method to consolidate carbon nanotube yarns and woven sheets and graphene sheets via the dehydration of sucrose. The resulting materials are lightweight and high strength. Sucrose is relatively inexpensive and readily available; therefore the process is cost-effective.

Method for Manufacturing a Thin Film Structural System

Applications include Earth- and space-based inflatable structures, and chemical and radiation sensors. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center has developed a technology that uses commercially available additive print manufacturing to add various levels of structural hierarchy to thin-film surfaces. The approach adds very little mass to thin films, but provides substantial performance enhancements, such as increased damage tolerance to tearing and ripping. NASA developed this technology to provide new and improved ways to produce robust, ultra-lightweight space structures such as solar sails, solar shades, and antennas. Beyond space applications, the technology is well suited for other thin-film applications.
