摘要: Compositions and methods relate to gas generants used in inflatable restraint systems. The gas generant grains include a fuel mixture having at least one fuel and at least one oxidizer, which have a burn rate that is susceptible to pressure sensitivity during combustion. The gas generant composition further includes a plurality of pressure sensitivity modifying glass fiber particles distributed therein to lessen the pressure sensitivity and/or to increase combustion stability of the gas generant. Such gas generants can be formed via spray drying techniques.

摘要: Methods of making and resultant compositions thereof, which include a gas generant having a coating including an inorganic combustion inhibitor. Such coated gas generants are useful in pyrotechnic compositions and ignition materials, and may be employed, for example, in inflatable restraint systems. The ratio of coated and uncoated gas generant bodies within an airbag inflator may be tailored to provide S-curve inflation performance. Spray application of aqueous mixture including the combustion inhibitor onto the gas generant body provides a rapid way to achieve a thin but robust coating.

摘要: An inflator assembly having an inflator body that forms a chamber wherein a quantity of a gas generating solid reacts to form gas. A quantity of gas treatment material is included to treat the formed gas to form a treated gas. At least one assembly exit opening permits the treated gas to exit the inflator assembly. The required gas generating solid has a flame temperature of no more than 1670 K with the inflator assembly having significant weight and volume reductions as compared to an otherwise identical performing inflator assembly that utilizes gas generating composition having higher flame temperatures.
