NickelLe nickel est un élément chimique, de symbole Ni et de numéro atomique 28.
Le nickel est un métal blanc argenté qui possède un éclat poli. Il fait partie du groupe du fer. C'est un métal ductile (malléable). On le trouve sous forme combinée au soufre dans la millérite, à l'arsenic dans la nickéline.
Grâce à sa résistance à l'oxydation et à la corrosion, il est utilisé dans les pièces de monnaie, pour le plaquage du fer, du cuivre, du laiton, dans certaines combinaisons chimiques et dans certains alliages. Il est ferromagnétique, et est fréquemment accompagné de cobalt. Il est particulièrement apprécié pour les alliages qu'il forme.

Résistance électriqueIndex. décimale : 620.1 Mécanique de l'ingénieur (mécanique appliquée) et matériaux Résumé : The increasing use of composites and plastics in demanding applications brings great advantages in physical and mechanical properties, but with compromises in electrical performance. Composite materials typically cannot provide adequate performance in application where electircal conduction is required. These electrical properties are becoming increasingly critical due to an escalating reliance on digital communications and controls.
Nickel nanostrands are a unique nanomaterial that brings value to many applications through improved properties, or by enabling altogether new material systems. Nanostrands are a three dimensionally interconnected metal nanostructure, with outstanding performance characteristics for inserting conductivity and electromagnetical capabilities. The unique features of nanostrands are identified, discussed, and compared. Multiple case studies are presented to demonstrate successful commercial products that are based on nanostrand technologies as well as several new products that are under development.Note de contenu : - Nanotechnology : New materials

[article]
Titre : High modulus structural body shop adhesives Type de document : texte imprimé Auteurs : Felix Koch, Auteur ; Andreas Lutz, Auteur Année de publication : 2018 Article en page(s) : p. 17-19 Langues : Multilingue (mul) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

The recent development of new toughening components allows to formulate structural adhesive which combine a high modulus but still offer excellent impact strength values. The increased adhesive modulus results in an overall improvement of the mechanical adhesive performance.

Transition vitreuseIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Primary and secondary structures that comprise modern aircraft are typically combinations of metals and lightweight carbon fiber- or glass fiber-reinforced polymer composites joined using high-performance adhesives. Historically, the adhesive bonding process required joined substrates to be cured in an autoclave to minimize voids and ensure reliable, high-quality parts. This procedure was time consuming as well as capital intensive. Aircraft OEMs are now seeking more cost-effective technologies, such as out-of-autoclave (OOA) curing that can produce parts more inexpensively than those fabricated via conventional autoclave processing.
In response to this trend, a new structural paste has been developed—designated Epibond® 100-A/B epoxy adhesive—that is formulated for OOA curing. The toughened epoxy exhibits outstanding mechanical properties at temperatures from sub-ambient to 149°C (300°F) and retains its high glass-transition temperature (Tg) values even after long-term exposure to hot/wet conditions. The advanced material also accommodates the needs of aircraft OEM and repair facilities for adhesives that can be stored at room temperature, are easy handle and apply, and oven cure in 1-5 hours. As a result, the new OOA paste adhesive can decrease labor time and production costs.Note de contenu : - AIRCRAFT ADHESIVE CHEMISTRIES : Resins - Toughening - HardenerS

ViscoélasticitéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Fracture tests were conducted on bulk samples of a rubber-toughened epoxy that models the fracture behavior of commercial structural adhesives. The samples were loaded with a variety of loading histories. The histories were selected to examine the dependency of fracture energy on loading rate, loading level, time under load, and recovery after loading. The results suggest that unless the load levels are a substantial fraction of the failure load, the loading history has little effect, at least for the time scales studied here. When the loads are high, however, the time under load becomes important and produces significant increases in toughness. If the sample is unloaded and allowed to recover, some but all of the additional toughness is lost. These results are consistent with a viscoelastic toughening mechanism and can be qualitatively explained with sample crack-tip blunting model.
