reportActive / Technical Report | Accession Number: ADA305101 | Open PDF

Abstract:

Test performed during the Spacelab Support Research and Technology Programme involving a Carbon Fibre Reinforced Plastic faced honeycomb panel have been rerun using an improved experimental technique. The original theoretical analysis has been revised using CFRP material parameters derived from a separate coupon test programme. Results from this programme have shown only small changes in material properties with decreasing temperatures. Discrepancies that were found between theoretical and practical panel performance have been put down to anomalous expansion coefficients and detail model problems. AN
