Abstract
The invention relates to a ceramic fiber felt or mat having one portion comprising a high temperature resistant ceramic fiber and another portion of lower temperature resistant ceramic fiber. The two portions are joined seamlessly by an intermingling and intimate relationship of the two fiber types during formation of the mat. The invention further provides apparatus for formation of such ceramic fiber composites and further provides for forming such composite ceramic fiber members into modules.
