Paper Title:
Prediction of Lifetime of Nylon 66 as an Airbag Material
  Abstract

Through the earlier accelerated aging tests (oven aging) of Nylon 66 yarns used in automobile airbags at the temperatures ranging from 60°C to 150°C, we have established a dynamics equation of tensile strength and aging time, and predicted the storage lifetime of this material in 25°C based on Arrhenius methodology and extrapolation method. Besides, the activation energy and thermal-oxidative aging parameter of Nylon 66 have been worked out from the test results. The study has showed that Nylon 66 airbag material has great thermal stability at high temperatures, and its storage lifetime under normal temperature is 4 times of its expected lifetime by design. The prediction results can be referenced for planning the service life of SRS or selecting airbag fabrics.
