Experimental Analysis of Elemental Composition of Materials used to Manufacture Gas Generators for Vehicle Airbag Modules

Abstract

The airbag is a part of the Supplementary Restraint System; along with the safety belt, it is the most important system that protects the driver and passengers if the vehicle collides with static or moving objects. Certain interrelated studies and measures are required so as to develop scientific, technical, design and technological foundations for producing airbag modules for various vehicle types: for example, determining the range of suitable domestic materials and alloys, as well as the compositions of pyrotechnic gas-generating charges to manufacture gas generators. We experimentally evaluated mechanical properties and elemental composition of materials that gas generator parts consist of, which allowed us to establish their domestic analogues. We determined the elemental chemical composition of pyrotechnic gas-generating charges (main and auxiliary) and the primer igniter charge. We used the following methods in our work: an experimental full-scale airbag module deactivation method for subsequently decomposing gas generators to obtain the necessary sample parts to investigate; a method for determining the microhardness of material samples to subsequently evaluate their ultimate tensile strengths; finally, laser-induced breakdown spectroscopy, X-ray fluorescence spectrometry, X-ray and infrared spectroscopy, ion and liquid chromatography, Raman spectroscopy and nuclear magnetic resonance to determine the elemental composition of materials
