| dc.description.abstractEn | 3D Carbon/Carbon composites have an important use in space propulsion and atmospheric re-entry of space objects. We propose a modeling approach for its non-linear mechanical and thermomechanical behavior based on the introduction of internal interfaces, under the form of cohesive and sliding zones located between the macro-constituents (bundles, matrix pockets). The interface model parameters have been identified from bundle push-out experiments at temperatures from ambient to 1000∘C. The model allowed reproducing successfully a 45∘ off-axis tensile test, only with initial damage and interface sliding. The sole incorporation of interface sliding as the only nonlinear phenomenon already allows to successfully reproduce the off-axis behavior. It is also correctly found that the material has a higher yield limit at high temperature, because its interfaces are closing due to thermal expansion of the bundles. The validity of the model does not encompass yet cases where progressive damage of the bundles occurs, as e.g. in torsion tests. | |
