Preparation method of fiber-reinforced ceramic-based/carbon-based composite material honeycomb structure
The invention discloses a preparation method of a fiber-reinforced ceramic-based/carbon-based composite material honeycomb structure, and belongs to the field of preparation of ceramic-based/carbon-based composite material honeycomb structures. According to the invention, a unique path is formed through a wiring method to lay the fiber bundles, so that the integrated molding preparation of the honeycomb structure of the fiber-reinforced ceramic-based/carbon-based composite material is realized, and the thickness consistency of the honeycomb structure is ensured. The contact wall surfaces of different units of the honeycomb structure form the same common wall surface through a routing method, so that the overall stability of the honeycomb structure is remarkably improved. The laying path and density of the fiber bundles are accurately controlled around the three-edged positioning column through a routing method, the unit size precision of the honeycomb structure is improved, and the consistency of the honeycomb structure units is ensured. The laid fiber bundles are pressed and shaped through a tablet press, overall densification forming treatment is carried out through a chemical vapor deposition (CVI) process, and the strength and the high-temperature resistance of the honeycomb structure of the ceramic-based/carbon-based composite material are improved. The invention has the advantages of integration, high strength, stable structure and high preparation precision.
