MONOLITHIC GAS GENERANTS CONTAINING PERCHLORATE-BASED OXIDIZERS AND METHODS FOR MANUFACTURE THEREOF

摘要

A gas generant for an inflatable restraint device (for example, an airbag system for a vehicle) is a monolithic compressed solid that has a linear burn rate of greater than or equal to about 1 inch per second at a pressure of about 3,000 pounds per square inch. The gas generant can be in the form of an annular disk having a plurality of apertures. The gas generant has at least one fuel and at least one perchlorate-containing oxidizer and is substantially free of polymeric binder. The monolithic grain gas generant may have a low initial surface area which progressively increases during burning. The gas generant is optionally formed by the methods of the present disclosure that include a spray drying process.
