Description
Die Erfindung betrifft einen mehrschichtigen Formkörper aus Kunststoffen mit unterschiedlichen Eigenschaften gemäß dem Oberbegriff des Hauptanspruchs. The invention relates to a multilayer molding of plastics with different properties according to the preamble of the main claim.
Dreidimensionale Bauteile aus glaserverstärktem Kunststoff sind seit Langem gängiger Stand der Technik. Sie bestehen zumeist aus einem Flächengebilde aus Verstärkungsfasern, das mit dem Kunstharz getränkt und vielfach in einer Form ausgehärtet wurde. Als Verstärkungsfasern werden neben Glasfaser auch pflanzliche oder Kohlenstofffasern und als Kunstharze Polyester-, Vinylester-, Epoxid-, oder Acrylharze verwendet. Three-dimensional components made of glass-reinforced plastic have long been common prior art. They consist mostly of a fabric of reinforcing fibers, which was impregnated with the resin and cured in many cases in a mold. In addition to glass fiber, vegetable or carbon fibers are used as reinforcing fibers and polyester, vinyl ester, epoxy or acrylic resins are used as synthetic resins.
Bei dieser Lösung dient die aufgebrachte Gelcoatschicht nur der optischen Verbesserung der Oberfläche. Die mechanischen Eigenschaften werden ausschließlich durch den faserverstärkten Kunststoff bestimmt. Diese faserverstärkten Kunststoffe zeichnen sich durch hohe mechanische und thermische Stabilität aus, sind jedoch andererseits relativ spröde und damit schlag- und stoßempfindlich. Die aufgetragene Gelcoatschicht führt nicht dazu, dass diese Sprödigkeit abgebaut wird. Im Gegensatz hierzu weisen Polyurethanformteile eine hohe Schlagzähigkeit auf. Nachteilig für Polyurethanformteile ist deren sehr niedrige Stabilität und schlechtes Schrumpfverhalten. Auch wenn weitere Polyurethanschichten zur Stabilisierung aufgetragen werden, bleiben das ungünstige Schrumpfverhalten und die schlechte Stabilität des gesamten Aufbaus erhalten. Eine Verstärkung von Polyurethanformkörpern durch Einarbeitung von Fasermaterialien ist derzeit technologisch nicht realisierbar, da mit den bisher bekannten Verfahren maximal 10 % Kurzfasern eingearbeitet werden können. Das Auftragen stärkerer Schichten von Polyurethan auf faserverstärkte Kunststoffe, zur Kombination der guten Eigenschaften beider Kunststoffe, scheiterte bisher an dem schlechten Verbund der Polyurethanschicht mit den faserverstärkten Kunststoffen. In this solution, the applied gelcoat layer only serves the optical improvement of the surface. The mechanical properties are determined exclusively by the fiber-reinforced plastic. These fiber-reinforced plastics are characterized by high mechanical and thermal stability, but on the other hand are relatively brittle and thus impact and impact sensitive. The applied gelcoat layer does not cause this brittleness is degraded. In contrast, polyurethane moldings have a high impact resistance. A disadvantage of polyurethane moldings is their very low stability and poor shrinkage behavior. Even if further polyurethane layers are applied for stabilization, the unfavorable shrinkage behavior and the poor stability of the entire structure are retained. A reinforcement of polyurethane moldings by incorporation of fiber materials is currently not technologically feasible, since a maximum of 10% short fibers can be incorporated with the previously known methods. The application of stronger layers of polyurethane to fiber reinforced plastics, to combine the good properties of both plastics, failed so far due to the poor bonding of the polyurethane layer with the fiber-reinforced plastics.
Die in der
Dabei besteht das Polyurethanformteil aus einem hochreaktiven Polyurethansystem, das in eine Negativform, insbesondere eine Kunststoffnegativform gespritzt wurde. Durch die Verwendung hochreaktiver Polyurethansysteme ist es möglich, Schichtdicken von mindestens 0,3 mm bis zu mehreren Zentimetern in die Form zu spritzen. In this case, the polyurethane molding consists of a highly reactive polyurethane system which has been injected into a negative mold, in particular a plastic negative mold. By using highly reactive polyurethane systems, it is possible to inject layer thicknesses of at least 0.3 mm up to several centimeters into the mold.
Ein derartiges Bauteil hat immer eine ansehnliche Außenseite und eine weniger attraktive Innenseite, da nur die Außenseite eine Abformung der Struktur der Form und somit relativ glatt ist. Durch Spannungen, die beim Ausschäumen der Kunststoff-Hartschaumschicht entstehen, weist die Oberfläche eines derartigen Formkörpers jedoch immer leichte Wellen und Krümmungen auf, die bei der Verwendung z.B. als Teile hochwertiger Karosserien störend wirken. Such a component always has a handsome outer side and a less attractive inner side, since only the outer side is an impression of the structure of the mold and thus relatively smooth. However, due to stresses which arise during foaming of the plastic hard foam layer, the surface of such a shaped body always has slight waves and curvatures, which in use e.g. as parts of high-quality bodies have a disturbing effect.
Deshalb ist es Aufgabe der Erfindung, einen mehrschichtigen Formkörper aus Kunststoffen mit unterschiedlichen Eigenschaften und ein Verfahren zu seiner Herstellung vorzuschlagen, der die hohe Formstabilität faserverstärkter Kunststoffe mit der Schlagunempfindlichkeit eines Polyurethanformkörpers vereint und dessen Außenseite eine spiegelglatte Oberfläche hat, die auch in Reflexionen keine Verzerrungen aufweist. It is therefore an object of the invention to propose a multilayer molding made of plastics with different properties and a method for its production, which combines the high dimensional stability of fiber reinforced plastics with the impact resistance of a polyurethane molding and the outside of which has a mirror-smooth surface that has no distortions even in reflections ,
