Thermosetting reactive resin systems such as epoxy, bismaleimide, and polyimide classes of material are brittle. The origin of brittleness is attributed to the high crosslinking density that exists in the fully cured forms of these materials. Traditionally, the toughness of these resins is...

3D printing uses computer control to fuse layers of polymers or powders into a three-dimensional object. Rutgers University researchers found a way to add to a fourth dimension – time – to the manufacturing process.

NASA's Langley Research Center has developed an optical method for detecting displacements and strains at ultra-high temperatures during thermo-mechanical testing. This innovation will provide displacement and strain measurements in...

Oxide coatings deposited in Glenn Research Center's Plasma Spray-Physical Vapor Deposition (PS-PVD) facility can be processed to be mechanically tough (erosion-resistant) and electrically conductive at room temperature. The electrically conductive phase...

During the last few decades, one of the most prevalent issues associated with the performance of aerospace composite materials has revolved around low interlaminar mechanical properties. The innovations described in this work outline a number of new and improved techniques for...

The configuration of carbon's electrons allows for numerous self-bonding combinations that give rise to a range of materials with varying properties. For example, transparent, super-hard diamonds and opaque graphite, which is used for both pencils and industrial lubricant, are...

Storage and transfer of fluid commodities such as oxygen, hydrogen, natural gas, nitrogen, argon, etc. are absolute necessities in virtually every industry. These fluids are typically contained in one of two ways: as low-pressure cryogenic liquids, or as...
