A "dry" adhesive, polyimide, with increased adhesion to materials used in spacecraft engineering is synthesized and studied. Its adhesion properties are estimated using the method of force–distance curves on the basis of scanning-probe-microscope functionality. A technique is developed for the ...
Spacecraft material on the ISS The International Space Station (ISS) uses a lightweight ceramic material, labeled Z93, to protect itself. This material has been used as a viable protective material for more than 10 years. Z93 is a zinc oxide pigment in a potassium silicate binder. The ma...

Scientists and engineers conducting research for the Air Force Research Laboratory's Materials and Manufacturing Directorate have identified ceramic materials that could increase the life of ceramic Hall thruster insulators for spacecraft, including sate
Since they are so versatile and offer so many beneficial properties for aircraft they are often used in other aviation vehicles besides passenger airlines and spacecraft. For example, they are often utilized for fighter planes, balloon gondolas, and glider structures and parts. ...
Luminescent materials SrAl2O4:Eu2+,Dy3+,ZnO:Eu3+,Li1+ and SiO2: Eu3+,Li1+ were planed for used as the trace marker of spacecraft.The space environment effects(including high vacuum,ultraviolet irradiation,cold and thermal cycling)on them were investigated.It was demonstrated that ZnO:Eu3...
Composite materials are heterogeneous materials composed of at least two constituent materials. Among the different types of composite materials, layered composite materials are quite common and are widely used for aircraft, spacecraft, wind turbine, automobile, marine, buildings, and safety equipment use...
