RUDERER - Bonding of lightweight carbon components

From zero to one hundred in 3.21 seconds: The new BMW S 1000 RR makes the hearts of enthusiastic motorcyclists beat faster. The 210 hp superbike is the result of ultra-modern production technologies. Ultra-light composite materials ensure driving dynamics, flexibility and stability. Various manufacturers rely on the ultra-modern industrial adhesives from RUDERER KLEBETECHNIK GmbH to bond a wide variety of lightweight components together quickly, reliably and visually flawlessly. The structural high-tech adhesive technicoll® 9411, for example, is suitable for carbon components in racing motorcycles. This reactive two-component adhesive enables absolutely tight, strong and material-friendly bonds, even for components with complex geometries. Structural adhesives can be integrated into any automated production process with short cycle times and withstand mechanical as well as chemical, dynamic and thermal loads in the long term. With their enormous performance, they ensure a safe driving experience on the asphalt and even more safety and stability in the production process.

Many different modern bonding applications and bonding technologies are used in the automotive industry today. The reason: bonded cars perform better in crash tests than welded ones. However, each individual component - whether in the body, engine, interior or electronics - is subject to special requirements and therefore needs a special adhesive. When structurally joining carbon fiber-reinforced plastics with each other and with other materials, manufacturers rely on high-performance adhesives that can handle this material mix, are resistant to high and low temperatures, can withstand chemical and mechanical stresses and significantly improve the performance of vehicles. This is the only way to design vehicles that are permanently safe and stable. Not only a guarantee for long-term product quality, but also a process accelerator in production and assembly.

Professional bonding of lightweight carbon components

The unique formulations of the modern adhesive systems from RUDERER KLEBTECHNIK GmbH have ensured perfect bonding results in almost all areas of application for decades. In motorsport, it is the high-performance 2-component structural adhesives based on epoxy resin (EP), polyurethane (PUR) and methyl methacrylate (MMA) that have been used successfully for years and achieve a higher application speed and productivity in series production. Due to the increasing use of lightweight carbon components, top-quality adhesive products are required that not only meet the highest demands in terms of functionality and durability, but are also visually appealing and in many cases must be black due to possible visible joints. An adhesive bond made of carbon, or more precisely carbon fiber reinforced plastic (CFRP), should react flexibly to tension, pressure and vibrations.

Carbon - the material of the future

Carbon is a composite material made of carbon fibers surrounded by a plastic sheath. The material most commonly used in the industry for the plastic coating is epoxy resin, although vinyl ester resins or polyamides are also sometimes used. In terms of stability, carbon is a very resistant and strong material with a low weight. In motorsport, the use of carbon allows maximum speeds to be achieved. Due to the strength and rigidity of the components, durability and safety can be increased. If this modern material is to be bonded together or in combination with other light metals, special adhesive formulations are required. RUDERER KLEBETECHNIK GmbH has launched high-performance two-component adhesives on the market under its own technicoll® brand, which bond composite materials without damaging them and thus maintain their outstanding strength.

High-performance: the reactive two-component adhesives from RUDERER

The black and pasty 2-component epoxy resin adhesive technicoll® 9464 is a very popular high-performance adhesive, particularly in motorsport. It ensures even force transmission when joining, so that stress cracks do not occur in the first place. The 2-component epoxy resin adhesive technicoll® 9464 perfectly compensates for geometric component tolerances and completely seals gaps. Due to its excellent chemical and temperature resistance, technicoll® 9464 is a popular bonding agent in the aerospace and rail transportation industries. The composition of the light yellow and viscous 2-component epoxy resin adhesive technicoll® 9469 is also perfectly matched to the surface of lightweight carbon components. Due to its long pot life of 100 minutes, the adhesive is ideal for large surfaces. The viscoplastic and reactive 2-component MMA adhesives technicoll® 9411 and technicoll® 9411/15 also achieve very high strengths. MMA adhesives are also characterized by excellent flexibility and bond a wide variety of materials such as plastics (ABS, CFRP, GRP, polyamides, etc.) and metals, even under continuous stress and constant exposure to the elements. The 2-component MMA adhesives technicoll® 9411 and technicoll® 9411/15 can be easily applied to vertical surfaces and are also suitable for powder coating.

Different types of plastic. Different adhesives.

If carbon fiber reinforced plastics are not produced with epoxies but with polyamides, a special surface pre-treatment is necessary. In this case, a primer serves as an adhesion promoter. However, the adhesive must be formulated to suit the modified surface. If CfK components have a peel ply, this is usually removed before bonding. As their water-repellent surface cannot be bonded particularly well despite one hundred percent cleaning, microfine cleaning (plasma pre-treatment) has proven effective. However, CO2 snow blasting or vacuum ultraviolet radiation (VUV radiation for short) can also remove dust and dirt particles in a way that is gentle on the material and the environment. As there is a vast number of different types of plastic on the market, it is all the more important to select adhesives carefully. In addition to the best possible adhesion properties, the geometry of the bonded parts plays just as important a role as the respective production conditions. As adhesive selection and professional processing are not self-explanatory and generally require detailed, application-related advice, RUDERER's adhesive experts offer free consultations at beratung@ruderer.de.

About RUDERER KLEBETECHNIK GMBH

RUDERER KLEBETECHNIK GMBH is your specialist for a wide range of premium industrial adhesives. We are a steadily growing family business in its second generation. Our head office is in Zorneding near Munich. With over 30 years of product and industry expertise in the field of bonding, we can provide our customers from industry and trade with optimum support and assistance with bonding projects - both with the right adhesive products and with the necessary know-how about composites, technologies and applications.

We are distributors and we are manufacturers. This guarantees our customers not only the best technological adhesive solution, but also very high product availability for fast, stable supply chains and the greatest possible flexibility, e.g. in terms of container size or delivery date changes, thanks to our large warehouse.

Our broad and deep range of adhesives includes many premium adhesives from well-known manufacturers such as technicoll, Araldite, Sika, H.B. Fuller, 3M, Panacol, Otto-Chemie, Kömmerling, Weiss-Chemie, Drei Bond, Loctite and Teroson. We select our suppliers carefully and ensure that we only include adhesives of outstanding quality in our portfolio.
