초록

Methods for making a pressed monolithic gas generant for an inflatable restraint device (for example, an airbag system for a vehicle) are provided. The methods include admixing a gas generant material with a ballistic performance modifier to form a mixture. The mixture is granulated. Then, a pressed monolithic gas generant grain is formed by applying pressure to the granulated mixture, where the grain has an actual density of at least about 95% of the maximum theoretical density. The pressure may be applied in a controlled manner to both side of the gas ...
