First Claim
Patent Images
1. A process for producing a hard consolidated form of heat generating thermite composition suitable for use in an inflator for an airbag restraint system of a motor vehicle, said process comprising:
- 1) mixing in a slurry medium until in intimate admixture;
a) about 20 to about 30 weight percent of a powdered metal fuel,b) about 40 to about 70 weight percent of a powdered metal oxide oxidizer,c) about 5 to about 25% weight percent of an essentially non gas-producing, non hot particulate-producing binder, andd) about 2 to about 10 weight percent of a supplemental oxidizing agent,2) extruding the resulting slurry mixture into a consolidated form,3) cutting the consolidated extruded slurry mixture into appropriately sized and shaped pellets, grains or wafer forms,4) drying the pellet, grain or wafer forms to remove the slurry medium therefrom, to form the consolidated extruded slurry mixture forms into hard consolidated shapes.
