Due to the size and weight limitation of the batteries, the use of batteries with high energy density is necessary. Adhesives and sealants are crucial for the construction of the battery modules and are needed for bonding, sealing and for thermal interface tasks. Note de contenu : - Tailor made adhesive solutions for battery applications
- Structural and crash-durable adhesives for battery enclosure applications
- Adhesives and sealants for battery enclosure applications

- Fig. 2 : Strength build-up measured by lap shear tests at 60, 80 and 100°C of a two component epoxide based adhesive for battery enclosure application for artificial ageint lap shear tests were performed initial (7d room temperature cure) and after 10 weeks exposure to salt spray. It was showed that lap searr strength is maintained
- Fig. 3 : Lap shear tests performed with a one component SMP sealant show that the cleaning with heptane of bare aluminum is sufficient to achieve a good adhesion. The lap shear strength were measured after 7 days room temperature cure as well as after exposure for 7 days at 70°C, 100 % r.h., immersion for 7 days in saltwater, 4 weeks climate change test, and 12 weeks salt spray test. The failure modes show a cohesive failure mode

[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.

Stabilité au stockageIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Since about twenty years structural adhesives are used in the body shop of an automotive line to bond vehicle body structures. 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.

RhéologieIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The use of multi material mix in the body structure in modern design for passenger cars generates issues with regard to significant temperature differences in joints caused by the different CLTEs of the different substrates when the car body passes the e-coat oven. These temperature gradients result in high tension and part deformation. New structural adhesive technologies must tolerate these thermally induced joint stresses.
