Composite Know-How

Composites Europe is one of the leading European trade fairs for composite materials. This year it will be taking place in Düsseldorf / Germany from October 7 to October 9. As leading solution provider for adhesives, sealants and functional coatings worldwide, Henkel will be appearing at Composites Europe with a range of innovative composite technologies for the automotive and aerospace industries. Experts will be on hand at Stand D44 in Hall 8a, providing information on a wide range of products and system solutions made by Henkel.

Composites in the automobile industry provide an excellent example of how Henkel is able to develop integrated solutions based on its technological expertise, process know-how and an especially coordinated adhesives portfolio. With weight reduction in modern vehicles having become essential – particularly in the face of strict exhaust requirements – as an avenue for decreasing both fuel consumption and CO2 emissions, lightweight construction technologies are constantly gaining in importance. Composite materials based on glass or carbon fibers combine savings in weight with enormous strength, thus also offering outstanding properties in relation to safety and crash behavior. With its Loctite MAX series, Henkel is offering polyurethane-based composite matrix resins that cure significantly faster than the epoxy products usually employed for the RTM process. Due to its low viscosity, the polyurethane resins penetrate and impregnate the fiber material more easily and less harshly, thus enabling very short injection times to be applied. Until now, there have been certain limitations in the use of lightweight components as they are restricted in the degree to which they can meet the requirements of the automotive industry in relation to cycle times and level of automation. In particular, composite components have been very rarely used for the visible body parts of production vehicles, as the requisite post-treatment of the surface for subsequent painting has been too costly and time-consuming, due to being based on manual processes. Working together with KraussMaffei and a network of further partners, Henkel has developed a new surface resin transfer molding process that enables the cost-effective manufacture of paintable composite components under mass production conditions. With their high-quality as-molded surface finish, these can be readily used for automobile body exteriors without the need for post-treatment. This has become possible thanks not least to the development of the Loctite three-component polyurethane-based matrix resin system from Henkel that contains not only the resin and hardener but also a high-performance release agent. This not only ensures that the component is easier to demold, it also means the process readily lends itself to both automation and efficient mass production. The partner network also includes carbon fiber manufacturer Zoltek and the sports car builder and development services provider Roding Automobile. The technology showpiece adopted for the development for this innovative process was a lightweight yet high-strength carbon roof segment of the 950 kg sports car, the superlight Roding Roadster R1.

During Composite Europe from October 7 to October 9, Experts will be on hand at the Henkel booth on Stand D44 in Hall 8a to provide information on a wide array of products and system solutions that the company is able to offer the composites industry.
