Abstract
An inorganic ceramic paper includes inorganic ceramic fibers and an inorganic binder system of fibers consisting essentially of silica. The binder system initially includes organic materials as well as the silica fibers, however, the organic materials are burned out of the ceramic paper. The silica fibers remain and flow so as to maintain the structure and integrity of the ceramic paper and hold the ceramic fibers together. Such a ceramic paper is useful in a variety of applications and is particularly useful as a filter in the inflator unit of an automotive airbag.
Claims8
A filter for use in an inflator unit of an automotive airbag comprising an inorganic ceramic paper including inorganic ceramic fibers and an inorganic binder of fibers consisting essentially of 100% silica, said inorganic ceramic paper being porous and free of all organic materials and having a tensile strength of at least about 500 grams per inch wherein said fibers consisting essentially of 100% silica have an average length of about 1 to about 3 inches.
