Lanxess: Contribution to Campus plastics database
Together with a number of international producers, the Lanxess subsidiary Bond-Laminates GmbH is participating in a project group that is collecting the standards-compliant material data of commercial composites in order to upload them to the Campus plastics database. The work of the project group is organized and coordinated by the Frankfurt-based AVK-Industrievereinigung Verstärkte Kunststoffe e.V. (German Federation of Reinforced Plastics) and the Institut für Verbundwerkstoffe GmbH (Institute for Composite Materials) in Kaiserslautern.
The aim was to develop harmonized test methods that comply with the relevant standards to enable comparable material characteristic values to be determined. Characteristic values that will be available in Campus as individual values and, in part, also as material-specific curves and diagrams, include the tensile modulus and strength, melting and glass transition temperature, and thermal expansion coefficient. Bond-Laminates will initially enter the material data for twelve different Tepex product types in the database, covering the most important part of the polymer matrices and reinforcing fibers of the Bond-Laminates product range.
One example of a material is Tepex dynalite 104-RG600(x)/47 %, a continuous-glass-fiber-reinforced semi-finished product with a polypropylene matrix. It is used in the large-scale production of front-end supports, engine compartment linings, and tank and tunnel covers for car underbodies, for instance. Tepex 210fr-C200(x)/45 % is another example. The composite material with continuous carbon-fiber reinforcement and a polycarbonate matrix has established itself in large-scale electronics applications.
