| titleOfInvention | SiC foam inner filling CfPreparation method of/C-glassy carbon ultrahigh-temperature vacuum heat-insulation circular tube |
| abstract | SiC foam inner filling C f / The preparation method of the C-glassy carbon ultra-high temperature vacuum heat insulation circular tube is characterized by comprising the following sequential steps: (1) winding carbon fiber prepreg cloth on the inner surface and the outer surface of the quartz glass round tube mould along the tube length direction to be tightly attached to the tube wall to serve as a fiber shell layer; (2) putting the prefabricated body into a high-temperature cracking furnace for cracking; (3) putting the treated prefabricated body into a pyrolysis furnace, introducing propylene and argon, and depositing to obtain pyrolytic carbon; (4) putting the treated prefabricated body into a vacuum pressure impregnation tank filled with a phenolic resin solution for pressure impregnation; (5) slowly curing the treated prefabricated body at the temperature of 10-150 ℃; (6) after solidification, putting the carbon fiber woven piece into a pyrolysis furnace for pyrolysis; (7) demolding; (8) filling SiC foam into hollow C f / C-glass carbon shell, and wrapping the fracture with prepreg cloth after filling; (9) and (4) putting the sample obtained in the step (8) into a chemical vapor deposition furnace, and introducing trichloromethylsilane, argon and hydrogen to obtain the compact SiC coating. |
