Work carried out as part fulfilment of MinTech contract no. PD/28/040 'Application of Carbon Fibre Composite to an Airbus'.This report contains charts of elastic properties and buckling coefficients of a simply supported compression panel, based on theory of multi layer plates of orthotorpic material, for a typical carbon fibre composite. In addition the optimum orientation of plies, of a three ply system, is considered for a corrugated compression panel together with the modifications necessary for other panel shapes. The computer programmes used are contained in the Appendix.
