Pales d'éoliennesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Over the decades to come, we will see a continuous increase in the proportion of wind power in the global mix. The goal is for wind farms to supply electricity at a price lower than that of fossil energy. As a result, the manufacturers of rotor blades and of dispensing and mixing systems for adhesives will have a number of challenges to overcome in the future.

Tests de sécuritéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : A new approach based on multiparametric fracture analysis evaluates the adhesive safety of double-sided adhesive tapes. As different test parameters create different test winners, it is necessary to define a well-thought-out evaluation concept that takes these inconsistencies into account. Note de contenu : - Traditional test methods with limitations
- Extensive evaluations using multiparametric fracture analysis

Soie d'araignéeLes fibres de soie sont formées de fibroïnes (protéines filamenteuses, appelées aussi spidroïnes2, composées de copolymères à blocs hydrophiles et hydrophobes) constituées à 25-30 % d'alanine et à 40% de glycine.
La soie d'araignée est un polymère dont la configuration moléculaire peut varier et rapidement s'adapter à la température et à l'humidité, ce qui fascine les chercheurs en biomimétique ou en robotique.
La soie d'araignée est notamment capable de « Supercontraction » (de 10 à 140 MPa de tension) quand elle s'humidifie (en plusieurs minutes quand l'hygrométrie dépasse 70 %), et plus rapidement quand elle est subitement mouillée. C'est ainsi que les toiles peuvent résister à la pluie, et au poids de la rosée voire accumuler plusieurs grammes d'eau sous forme de gouttes, à partir de la bruine par exemple. La thermostabilité varie aussi selon le degré de supercontraction
Structures multicouchesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Adhesives have to meet a wide variety of requirements that range from high levels of adhesion to easy removability. However, it is hard to achieve both these properties at the same time. In the case of floor coverings, the emphasis is often on adhesion, which can make the flooring difficult to remove. In addition, fossil-based adhesives raise concerns about sustainability and recycling. One solution to these problems is a bio-based adhesive system.
