The subject of study was thin-walled profile made of carbon-epoxy laminate. Specimen had an open cross-section with a symmetrical arrangement of the laminate layers. In presented work, experimental and numerical tests of the axial compression process were carried out up to the loss of load-carrying capacity. Numerical study was carried out using nonlinear analysis of construction stability - Newton-Raphson method. The results of numerical analysis were confronted with the experimental study, which provided the same quality of prepared FEM model.The subject of study was thin-walled profile made of carbon-epoxy laminate.
