Overhead presentation. Sandwich panels with carbon fibre reinforced plastics (CFRP) face sheets are very common in satellite structures due to high stiffness to weight ratio. Radiator panels are still from aluminium face sheets due to high coefficient of thermal expansion (CTE) of the integrated heat pipes. The development of low CTE metallic profiles for the integration into CFRP structures is presented in the paper. A technique to integrate metallic condenser tubing into CFRP sandwich panel is shown. The task to reduce the CTE mismatch of metallic components, embedded in CFRP structures has been achieved with two developments: Low - CTE composite heat pipe for integration into CFRP radiator panels; Composite structure consisting of staggered panels for thermal and structure performance. Both concepts are now being qualified for application into future spacecraft.
