OCULUS – Optical Coatings for Ultra Lightweight Robust Spacecraft Structures

OCULUS - Optical Coatings for Ultra Lightweight Robust Spacecraft Structures

Geringes Gewicht bei hoher Lebensdauer und Genauigkeit von Spiegeln von Weltraumteleskopen? Neue Materiallösungen sollen es möglich machen! Ziel ist die Kombination innovativer Produktions­prozesse von carbonfaserverstärkten Kunststoffstrukturen (CFK) mit hochreflektiven Beschichtungen. Auf diese Weise können leichte optische Spiegel für die Raumfahrt (z.B. Erdbeobachtung und Astronomie) gefertigt werden, die vielseitige Vorteile gegenüber herkömmlichen Spiegeln besitzen:

  • Thermische Stabilität (keine Kühlung notwendig)
  • 80% bis 90% geringere Masse
  • Modularisierung der Produktion (große Stückzahlen mit einem Werkzeug herstellbar)
  • Multifunktionale Oberflächen durch smarte Beschichtungen
  • Verfahren auf den Maschinenbau übertragbar
