Buckling of Thin-Walled Angle Column Made of Hybrid Laminate Under Axial Compression

This paper presents an investigation into the eigenproblem of angle columns manufactured using flax- carbon laminates. The first three eigenmodes and their corresponding critical load values for columns under axial compression were determined. The analysis covered six configurations with the same layer arrangement. The study also analyzed the impact of changing individual layer materials on bifurcation load values. A comparison was made showing differences in bifurcation load values for carbon and flax-carbon configurations compared to all-flax configurations for all three modes. The results suggest that replacing flax layers with carbon layers can extend the operational range of the system in the linear area. Additionally, the study explored the effect of using a single carbon layer versus a pair of carbon layers in hybrid configurations on critical load values. Results indicated that a higher bifurcation load value was obtained with a single carbon layer compared to a pair of symmetric carbon layers in selected configurations.
