Henkel at JEC Europe 2015
Adhesive Solutions and Composite Materials
JEC Europe is the world’s biggest fair for composite materials. This annual trade show at Porte de Versailles in Paris, France, will be open for business from March 10 through March 12, 2015. Henkel experts will be available at Stand F17 in Hall 7.3 to provide information on the wide range of products and system solutions that the company is able to offer to the composites industry.
Composites for the aerospace industry must meet a wide range of requirements. In addition to weight reduction, performance and manufacturing are in focus. With a weight saving of up to thirty percent over current surface films and a minimized pre-paint preparation, the innovative, epoxy-based surface film LOCTITE EA 9845 LC Aero Henkel exactly meets these requirements. Due to its copper mesh, LOCTITE EA 9845 LC Aero also provides excellent protection against lightning strikes.
Cost-efficient large-scale production of composite components for the automotive industry
Composite materials based on glass or carbon fibers combine savings in weight – leading to reduced fuel consumption and CO2 emissions – with enormous strength, thereby offering enhanced safety and good crash behavior. As a global leader in the supply of adhesives, sealants and functional coatings, Henkel works closely with its industrial customers to create tailor-made and integrated solutions designed to meet the challenges that lightweight construction brings to the automobile industry, particularly in relation to cost efficiency and suitability for volume production.
Now a fiber-reinforced composite leaf spring based on the polyurethane matrix resin LOCTITE MAX 2 from Henkel is being used in the chassis of the new Volvo XC90, a premium crossover SUV of which the innovative rear axle concept is to serve as a platform for other model series. BENTELER-SGL, a leading manufacturer of composite components for automotive applications, is aiming to produce several hundred thousand of these leaf springs per year. In its alliance with BENTELER-SGL aligned to the development and large-scale production of a composite leaf spring for Volvo Cars, Henkel has contributed in particular its process know-how in relation to RTM (resin transfer molding) so as to further optimize the cycle times that occur in the manufacture of fiber-reinforced components. Because of its low viscosity, the polyurethane matrix resin LOCTITE MAX 2 from Henkel rapidly fills the mold and quickly yet gently impregnates the fiber material, resulting in short injection times. With the curing rate also substantially faster than that of epoxy resins, cycle times are shorter overall.
The use of composite components for the outer shell of standard production vehicles has remained a rarity due to the need for reworking the surface prior to painting – always time-consuming and invariably done by hand. Working with KraussMaffei, however, Henkel has now developed a process for the manufacture of glass or carbon fiber reinforced components for exterior applications using the Surface-RTM process (S-RTM). This generates a surface of sufficiently high quality to meet even vehicle body requirements. And it has all been made possible by LOCTITE MAX 3. The newly developed three-component matrix system from Henkel based on polyurethane contains not only the resin and hardener but also a high-performance internal release agent. This ensures the easy removal of the component from its mold and thus a surface that can be immediately painted or adhesive-bonded. At JEC Europe, Henkel will be showing the Roding Roadster R1 of which the light and exceptionally strong roof module has been manufactured using this process.
Henkel will also present a new lightweight inner door shell of the Roding R1 manufactured with a LOCTITE MAX resin demonstrating the excellent flow characteristics of that resin family on very complex geometrical shapes. The lightweight concept is complemented by corresponding assembly adhesive solutions.
During JEC Europe, scheduled for March 10 through 12, 2015, Henkel experts will be available at Stand F17 in Hall 7.3 to provide information on the wide range of products and system solutions that the company is able to offer the composites industry.
