The new propellant aims at low cost, small size of inflators, featuring low toxicity of not only raw materials of the propellant but also effluent gases, particulates and residues generated on deployment of an airbag. No hygroscopicity and low hazard of the propellant will make manufacturing, transportation, and handling easy. The performances of the propellant were evaluated by strand test, pressure chamber test, 7.5 l tank test, 60 l tank test, and airbag deployment test. The strength of the pellet of the new propellant was evaluated by a small ball drop test. Abstractde Durch Zusammenarbeit zwischen einem Universitätslabor und drei Firmen wurde ein nichtazidhaltiger Treibstoff für Kraftfahrzeug-Airbag-Gasgeneratoren entwickelt mit der Zusammensetzung Azodicarbonamid(ADCA), Kaliumperchlorat und mit Zusätzen wie z. B. Abbrandkatalysatoren, Binder u.a. Der neue Treibstoff zeichnet sich aus durch niedrige Kosten, geringe Größe des Gasgenerators, niedrige Toxizität nicht nur des Ausgangsmaterials für den Treibstoff sondern auch der freigesetzten Gase, Partikel und Rückstände, die beim Aufblasen des Airbags erzeugt werden. Der Treibstoff ist nicht hygroskopisch und wenig gefährlich und erleichtert dadurch Herstellung, Transport und Handhabung. Die Leistungsdaten des Treibstoffs wurden bewertet durch den Strangtest, Druckkammertest, 7,5-Liter-Tanktest und Airbag-Aufblastest. Die Festigkeit des Treibstoffgranulats wurde mit dem kleinen Ball-Drop-Test bestimmt. Abstractfr Un laboratoire universitaire et trois entreprises ont développé en coopération un propergol non azidique pour générateurs de gaz d'airbags de véhicules automobiles, qui se compose d'azodicarbonamide, de perchlorate de potassium(KClO4) et d'additifs tels que catalyseur de combustion, liants et autres. Le nouveau propergol se caractérise par un faible coût, des générateurs de gaz de petite taille, une faible toxicité non seulement des substances brutes du propergol, mais aussi des gaz effluents, des particules et des résidus générés lors du déploiement de l'airbag. Le propergol n'est pas hygroscopique et est peu dangereux, ce qui en facilite la fabrication, le transport et le maniement. Les performances du propergol ont été évaluées par le test du cordon, le test en bombe manométrique, le test du réservoir de 7,5 litres et le test de gonflement d l'airbag. La résistance du granulé de propergol a été déterminée au moyen du petit test de Ball-Drop. Citing Literature Volume23, Issue1February 1998Pages 28-33 RelatedInformation
