NASA TechPort - Project Data
Future NASA space mirror requirements call for an order of magnitude improvement in areal cost over current technologies. With this goal in mind, Semplastics will leverage existing in-house technologies to develop an ultra-low cost, lightweight, molded, chalcogenide glass-silicon oxycarbide (SiOC) composite mirror component.
NASA is Working on Electric Airplanes - Universe Today
For this reason, NASA has partnered with the commercial industry to develop electric aircraft, which they hope will provide a fuel- and- cost-efficient alternative to commercial jets by 2035.
Silicon nitride - Wikipedia
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si3 N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is
Carbon Fibre Reinforced Silicon Carbide Composites …
Abstract Ceramic matrix composites (CMC), based on reinforcements of carbon fibres and matrices of silicon carbide (called C/SiC or C/C-SiC composites) represent a relatively new class of structural materials. H. Hald, H. Weihs, B. Benitsch, I. Fischer, T. Reimer
Silicon Carbide (SiC): Properties and appliions | …
Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
