| Popis: | For applications in thermal structure engineering, static and dynamic mechanical properties of 3D braided SiC/SiC composites after oxidation were investigated and the effects of interface between fibers and matrix were revealed. The results showed that composites with combined (PyC + SiC) multilayer interface (denoted as K–C/S) were superior to those with a single interlayer or without an interlayer. After oxidation, K–C/S showed the least weight changes, the highest flexure strength, small internal friction, and highest storage modulus. The outside SiC interface of K–C/S protected the PyC interface from further oxidation. Thus, K–C/S showed highly advantageous with regard to both static and dynamic properties after oxidation. |
