Abstract:The longitude tensile properties of 3-Dimension-4-directional(3D-4d) braided C/SiC composites(CMCs) were investigated with the help of a double scale model. This model involves micro-scale and unit-cell scale. In micro-scale, the tensile properties of fiber tows which involves matrix cracking, interfacial debonding, and fiber failure are studied. The unit-cell scale model can reflect the braided structure and simulate the tensile properties of 3D-4d CMCs by introducing the tensile properties of fiber tows into it. Quasi-static tensile tests of 3D-4d braided CMCs were performed on a PWS-100 test system. The predicted tensile stress-strain curve by the double scale model is in good agreement with that of the experimental results. © 2017, Wuhan University of Technology and Springer-Verlag GmbH Germany, part of Springer Nature.
