A process for producing a ceramic fiber blanket is disclosed. The process comprises the steps of preparing a laminar pile of ceramic fibers that comprise 35 to 65% by weight of alumina, 35 to 65% by weight of silica, less than 10% by weight of another metal oxide and a lubricant, superimposing a web of organic fibers on one or both sides of the pile, punching the resulting assembly with barbed needles, and removing the lubricant. The ceramic fiber blanket has a uniform thickness and a tensile strength high enough to withstand rough handling. |
