Test setup for CTE measurement
Test setup for CTE measurement

  • Design and assembly of a test setup for the measurement of thermal elongation of CFRP struts for extreme thermoelastic stability requirements
  • Screwed and clevis end fittings made of CFRP and Invar (reference) have been investigated
  • The special challenge for the design of the test setup was to achieve the high accuracy that is required for measuring very low CTE
  • The CTE for the struts have been measured in the temperature range of -180°C to +70°C
