HPS - High Performance Superinsulation for Long Term Vacuum Stability
Multilayer insulation is the leading-edge technology to thermally insulate high temperature gradients under vacuum conditions. We extended our activities into the field of insulation systems for cryogenic application in 1993. Such insulation systems are to be developed for liquid gas systems according to technical requirements.
Using the experience from space business and from former cryogenic programmes at AAE the spacer material has been identified as the crucial material for application in automotive tank systems because of important effects of the spacer for the thermal performance, flammability of insulation and influence to degradation of vacuum.
We want to cooperate with the European Space Agency (ESTEC) to carry out data base research for materials and achieve testresults for similar applications. A close partnership with the Technical University in Vienna, Institut für allgemeine Physik, Prof. Rudolf Dobrozemsky has been established to investigate vacuum technology and the outgasing of materials. And finally the University / research institute Forschungszentrum Karlsruhe, Dr. Holger Neumann shall perform tests of different multilayer insulation compositions with different types of spacer materials. Further tests are planned for oxygen-compatibility.
The final goal of this programme is the generic qualification of insulation which can be adapted for use in future technical applications. Planning:
- Phase I Investigation/development of materials and tests
- Phase II Selection of materials versus tests
- Phase III Performance of tests
