Langues : Multilingue (mul) Catégories : Assemblages collés Bois lamellé collé Collage Essais de résilience Essais dynamiques Matériaux -- Fatigue Mesure Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Glued-in rods represent a joint type commonly used in timber engineering when high strength, rigid, and aesthetic connections are looked for. While there is extensive research on glued-in rods in softwood, there is still a lack of research on hardwood. Due to climate change and expected reorganisation in the structure of forests, it is to be assumed, that significantly more hardwoods will be used in the construction industry.

Adhesive tapes and structured bonding - The best of both worlds / Christina Barg-becker in ADHESION - ADHESIVES + SEALANTS, Vol. 15, N° 4/2018 (2018)  

[article]  inADHESION - ADHESIVES + SEALANTS > Vol. 15, N° 4/2018 (2018) . - p. 16-19 Titre : Adhesive tapes and structured bonding - The best of both worlds Type de document : texte imprimé Auteurs : Christina Barg-becker, Auteur ; Reinhold Domanski, Auteur Année de publication : 2018 Article en page(s) : p. 16-19 Langues : Multilingue (mul) Catégories : Adhésifs structuraux Collage structural Rubans adhésifs Index. décimale : 668.3 Adhésifs et produits semblables Résumé : In the case of structural bonding with special adhesive tapes, the substrates are permanently bonded together for the purpose of withstanding extreme loads. In contrast to the pressure-sensitive adhesive tapes, their activation takes place only by means of a chemical reaction (usually heat). Structural adhesives enable the absorption of high forces, withstand high temperatures, meet the highest safety-related requirements and create a permanently stable bond. For which applications are these adhesive films suitable and what should be considered in their use?

The basis is a special low-viscosity epoxy resin matrix. The innovative feature of this system is its combination of low viscosity and outstanding wash-out resistance. These adhesives also cover a very large bonding range. To be specific, they exhibit excellent properties on the zinc-magnesium coated steel substrates we have been hearing so much about lately.
