Various compression tests show significant inhomogeneous stress states, leading to a multiple failure mode. In the new approach different lubricants between specimen and loading equipment were tested to reduce multiaxial stress state in the loading area. The test method was modelled by Finite-Element Analysis (FEA) using a multiple body contact model including different coefficients of friction between the bodies as well as plasticity. The unidirectional cylindrical specimens were tested under compression. The model predictions and the tests show good agreement in the deformed shapes under loading. Depending on the lubricant the failure changes from fibre buckling to a pure cross tensile failure. However, the compression strength is not highly dependent on the edge modification, whereas deviation and failure are.enCFRPCompression failureCompression strengthFEAStress stateTestingConference PaperOther
