| 摘要 |
The invention includes a method for densifying one or more porous preforms, including the edges and surfaces of one or more preform, when using a liquid precursor. The method includes covering at least a portion of the porous preform with an insulating material to insulate at least a part of the preform. The preform is submerged in a precursor liquid which is heat-decomposable. The preform is heated in the precursor liquid at a temperature sufficient to decompose the precursor liquid within the preform and to deposit a decomposition product of the precursor liquid within the preform. The heating of the preform is continued in the precursor liquid until at least part of the insulated portion of the preform, which would not densify in this process without insulation, is densified. |
