ULTIMAL - Forschung und Entwicklung von ultraleichter Thermalisolation

Short Description

The project ULTIMAL focuses on the development of ultra-light thermal insulation for vacuum applications in space. Utilizing nanotechnologies such as the innovative processes of electrospinning and electrospraying, considerable weight savings shall be achieved when compared to current multi-layer insulation.

Taking maximum benefit from the results of the projects "Non-flammable Superinsulation" (ASAP 4 and ASAP 5 funding) and "Ultra-light Multi-layer Insulation with Nano-fiber Spacer" (demonstration of feasibility and use funded by ESA in the frame of the Innovation Triangle Initiative) the technology shall be further developed and pre-qualified for use on spacecraft.

Even further mass savings are investigated, which may be achievable through the use of ultra thin foils. The potential of optimizing cryogenic insulation by use of Nano-fiber spacer is studied. A dedicated work package covers the safety aspects of nanotechnology in this specific use.

Continuing the current cooperation in superinsulation research, the scientific partners Austrian Research Institute for Chemistry and Technology (OFI) and the Vienna University of Technology, Institute of General Physics shall again contribute their strengths in the fields of chemistry and physics. The Institute of Materials Science and Technology of the Vienna University of Technology shall add their expertise in the characterization of nanostructured materials.
