UTILIZATION OF PROPELLANTS FOR INFLATOR AND BELT RESTRAINT SYSTEMS
RÉSUMÉ
In the past, most airbag gas generators for inflator systems were based on sodium azide (NaN3) containing propellants. But in the meantime also azide-free propellants are being used such as nitrocellulose (NC) containing systems and double base propellants (Eurobag-gasgenerator).
At the Fraunhofer Institute in Pfinztal many investigations have been conducted for the qualification of different gas generators. In this connection, safety aspects, internal ballistics behavior, stability and life time of the propellants have been measured as well as the reaction products in order to find out the toxicity of the products.
The results of these investigations will be discussed in this paper.
