Abstract (en)
[origin: WO2009023119A2] A multi-composition pyrotechnic material is provided for an inflatable restraint device (for example, an airbag system or pretensioner for a vehicle). The multi-composition pyrotechnic material can be a gas generant, a micro gas generant, or an igniter, for example. The multi-composition pyrotechnic material comprises a first pyrotechnic material that defines one or more void regions. A second pyrotechnic material, compositionally distinct from the first pyrotechnic material, is introduced into at least one of the void regions and forms a second region of the pyrotechnic materials. The second composition can be introduced to the void regions in the form of a slurry. Methods of forming such multi-composition pyrotechnic materials are also provided.
