Buckling and Postbuckling of Stiffened Thin Skinned Carbon Fibre Composite Panels

摘要

Initial investigations into the manufacturing and testing of Stiffened CarbonFiber Composite Panels for buckling and postbuckling strength are reported. Five panels were manufactured using different manufacturing techniques and a full description of these panels is given. All panels were tested to failure in an INSTRON compression testing machine. Buckling mode shapes were observed through the use of the Shadow Moire Fringe technique and strain measurements were obtained using resistive strain gauges. Linear finite element analysis was also carried out to compare predicted budding loads with experimental results.
