...res of plastic honeycombs or epoxy resin laminates with two-component acrylates or polyurethane hotmelts and then laminated with a decorative film. Adhesives Suppliers The leading adhesives suppliers in Germany are: Henkel Teroson GmbH, Sika AG, Araldite Polymer GmbH, Gurit-Essex, Kömmerling, H.B. Fuller, Tivoli Klebstoff GmbH, Helmetin and 3M. While Henkel Teroson has the widest product range (Macroplast, Macromelt, Terokal), Sika is clearly focusing its PU adhesives (Sikaflex) on flexible bo...

...he arithmetic mean calculated. The study was performed on polyether ether ketone PEEK 450 G (manufacturer: Victrex plc, UK) using standardised, injection-moulded tensile rods (DIN 53455). The adhesive was a two-component epoxy resin system (grade: Araldite AV138M + HV998, manufacturer: Ciba Speciality Chemicals, Basle/Switzerland). Surface Analysis The untreated and treated polymer surfaces were examined so that the adhesion mechanisms involved in the bonded joints could be established and the...

... the rear spoiler of a high-performance sports car (Fig.2) produced by CBS, an Italian supplier to the automobile industry, from several CFRP components. The CFRP components are bonded with a two-component toughened epoxy adhesive (grade: Araldite2015, manufacturer: Vantico Ltd, Duxford/UK). The combination of high strength and high toughness of the adhesive used permits the realisation of bonds that withstand the high dynamic loads, even at the sports car’s top speed of 320km/h. The adhesive bo...

Incorporation Into The Thermoset Systems In this project, two EP resins, one trifunctional and one tetrafunctional (Araldite MY 720 and Araldite MY 0500) from Ciba were used with diaminodiphenylsulphone (HT 976, also from Ciba) as the hardener. The extrudate was added to the thermoset mixes in quantities of 5-60 % by wt. To produce the EP resins, the decomposed pol...

...y resin matrix. The transverse tensile strength of test specimens with this size is only a quarter of the strength of composites with EP-sized fibres, as proved by the comparatively poor adhesion. The matrix material used was the epoxy resin system Araldite LY556/HY17/DY070 (manufacturer: Ciba Spezialitäten GmbH). On a laboratory winder, cross-ply composites (0°/90°/0°/90°)sym with a fibre-volume content of 58 ± 1,5% and different layer structures were produced (each with eight layers): - 8EP: e...

Experimental Technique The matrix material used was an epoxy resin based on bisphenol A (grade: Araldite LY556, manufacturer: Ciba Geigy) and an aromatic amine curing agent (grade: AralditeHY932). The filler is a highly structured conductive carbon black (grade: PrintexXE2, manufacturer: Degussa) with a DBP absorption of 380ml/100g. This was disp...

...neratively produced. The machines themselves are still essentially prototypes rather than fabricators. While their construction speed is sufficient for prototypers, they are too slow for production. One rapid system is the Araldite Digitalis, a new development from Huntsman Advanced Materials GmbH, Basel, Switzerland, which was presented in 2008 (Fig. 6). This promises a considerably higher construction speed with more homogeneous parts and lower costs and can be deployed on a targeted basis for...

The various raw material suppliers recently adapted their basic thermolatent special types of epoxy resins, i. e. the brands of Baxxodur, Voraforce, Epikote and Araldite, to fit fast curing [12–15]. Viscosities are below 200 mPas, which is a value extraordinarily low. This makes it possible to soak the semi-finished fiber product within a period clearly below one minute, subject to the respective component; cure speed is a...
