An asymmetric 2D braiding strategy for balancing hoop and axial strength in SiC/SiC composite nuclear fuel cladding
To address the challenge of inverted hoop and axial strength in SiC/SiC composite cladding for nuclear reactors, this study introduces an innovative asymmetric two-dimensional (2D) braided design. A multi-scale model was constructed to predict the mechanical properties of the claddings with different braiding structures. Leveraging a chemical vapor infiltration/chemical vapor deposition (CVI/CVD) process, gradient braided specimens with braiding angles of 30°/45° and 50°/42° were fabricated to systematically reveal the regulatory mechanism of the braiding angle on mechanical properties. Results indicate that the inner braid angle has a more significant impact on mechanical properties, while the outer braid design can compensate for the mechanical property deficiencies caused by the inner braid angle, thereby overcoming the inherent conflict between hoop and axial strengths in traditional symmetric designs. Raman spectroscopy revealed a residual compressive stress of −2.07 GPa in the large-angle braiding structure (50°), contributing to improved hoop strength via prestress strengthening. Parameter weighting analysis indicated that the inner-layer braiding angle primarily dictates hoop strength, while axial strength is co-regulated by both braiding angle and porosity. This research provides a theoretical foundation for multi-objective optimization of nuclear fuel cladding performance.
