Advancements seem to be emerging almost daily—especially as they relate to the power source, which includes battery pack design, engineering and assembly. In recent years, several factors have accelerated the growth of the emerging electric and hybrid cars market. Strict government regulations are obliging vehicle manufacturers to be involved in the electrification of their fleet. At the same time, financial incentives from governments are enticing consumers to buy electric or hybrid vehicles. Battery packs for electric vehicles face many of the same challenges that the vehicles themselves must overcome—safety, reliability, durability and consumer confidence. Adhesives are already onboard to address these issues, and more.

Setting sail with structural adhesives in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 25, N° 9 (09/2018)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 25, N° 9 (09/2018) . - p. 31-35 Titre : Setting sail with structural adhesives : The ETS Rafale II student team built a carbon epoxy C-Class hydrofoil catamaran using Scott Bader structural adhesives Type de document : texte imprimé Année de publication : 2018 Article en page(s) : p. 31-35 Langues : Américain (ame) Catégories : Adhésifs structuraux Bateaux -- Conception et construction Bateaux -- Matériaux Composites à fibres de carbone Index. décimale : 668.3 Adhésifs et produits semblables Résumé : A team of graduate engineering students from the École de Technologie Supérieure (ÉTS) in Montréal, Canada, recently finished building Rafale II, an all-composite C-Class racing hydrofoil catamaran. It features redesigned carbon fiber epoxy prepreg hulls and cross beams, which are stiffer and 25% lighter while providing 15% more displacement volume. The speed and handling of the catamaran has also been improved by designing lighter, stronger and better-performing pairs of new epoxy carbon fiber L-foil dagger boards and T-section rudder hydrofoils, which provide a higher lift/drag ratio and greater stability when hydrofoiling. The first ETS Rafale project started in early 2014 with a relatively small budget of CDN$130,000 (~ $99,000). However, the students received considerable support and technical advice from over 40 project sponsors, including Scott Bader North America (then Scott Bader ATC), which sponsored both Rafale I and II and provided composite resin, tooling, and structural adhesive products, as well as technical support. This second ETS team is building on the experiences of the Rafale I team. They have been at the forefront of composite technology and design, having influenced both the creation of the World Speed Sailing Committee and modern racing yacht designs, including the America’s Cup class AC72, AC45 (wingsail design) and AC50 racing catamarans. Note de contenu : - A vinyl ester resin was used in the heated molds for the new hull sections to cover the wire elements prior to the second mold tool infusion - To minimize weight, Rafale II was redesigned using FEA and CAD technology based around a carbon fiber epoxy prepreg system and assembled using a structural adhesive - Using a urethane acrylate-based structural adhesive** in the corners of the hull mold not only avoided stress concentration points and prevented any dry areas or air inclusions in the finished parts, but also made the tool far less prone to corner damage during part demolding - The new carbon fiber epoxy prepreg hull half sections for Rafale II were molded by low-pressure vacuum bagging out of autoclave using heated tooling - To minimize weight, the two halves of the hull were bonded together using a structural adhesive (no fastenings required) - Both the boat and the two-man team of Maxime Loiselle at the helm and Olivier Leduc as crew performed extremely well in Miami during the U.S. Foiling Week En ligne : https://www.adhesivesmag.com/articles/96458-setting-sail-with-structural-adhesiv [...] Format de la ressource électronique : Texte Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32007 [article]

Waterborne acrylic PSA technology with high-temperature performance / Jong Guo in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 25, N° 9 (09/2018)  

[article]  inADHESIVES & SEALANTS INDUSTRY (ASI) > Vol. 25, N° 9 (09/2018) . - p. 25-28 Titre : Waterborne acrylic PSA technology with high-temperature performance : A new waterborne technology offers excellent adhesion properties and high temperature performance Type de document : texte imprimé Auteurs : Jong Guo, Auteur ; Graeme Roan, Auteur Année de publication : 2018 Article en page(s) : p. 25-28 Langues : Américain (ame) Catégories : Adhésifs -- Propriétés thermiques Adhésifs en phase aqueuse Adhésifs sensibles à la pression Monomères Polyacryliques Réticulants Test d'immersion Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Pressure-sensitive adhesives (PSAs) are ubiquitous in many applications, such as labels, packaging tape, medical tapes, automotive tapes, and graphics. Two major chemistries are used in PSAs: acrylics and rubber in the forms of solvent-based, waterborne, or hot melt. Waterborne acrylic PSA offers many advantages: good ultraviolet (UV)/thermal stability, low cost, low hazards, environmental friendliness, and high solids. Significant performance gaps between waterborne and solvent PSAs traditionally limit the use of waterborne technology in some more demanding applications. Industry has been pushing the boundary of the waterborne technology to close these gaps. A new waterborne technology with excellent adhesion properties and high-temperature performance has been developed. This new technology has applications in the specialty tape market with emulsion technology; it matches and, at times, surpasses the well-established solvent acrylic and UV syrup technologies that dominate that space today.
