ABSTRACT:
A heat-resistant alumina fiber mat contains an accumulated mass of alumina staple fibers and continuous alumina filaments. The accumulated mass is sewn with the continuous alumina filaments. A process for producing a heat-resistant alumina fiber mat comprises accumulating a precursor of alumina staple fibers to obtain an accumulated mass, sewing the accumulated mass with continuous filaments to give a sewn mass and then sintering the sewn mass. The continuous filaments may be continuous alumina filaments or a precursor thereof.
