Abstract: Mono-dispersed silica spheres were prepared as template by st?ber method. Based on this template, the ordered nanoporous ceramic joints on the C/SiC composites were successfully fabricated for the first time by preceramic polymer techniques and the condition was optimized. Two different joining methods, directly soaking (DSM) and soaking after the first joining (SJM), were used for joining the ordered nanoporous ceramic joints of the C/SiC composites. The result shows that the bending strength of the joints by DSM and SJM is about 20.5 and 82.4 MPa, respectively, suggesting SJM more suitable for joining C/SiC composites.
