Experimental Research on Permeability of Airbag Fabrics at High Pressure Differential

摘要

The air permeability of airbag fabrics was measured at high pressure differential up to 200 kPa. It was found that permeability varied with pressure differential nonlinearly. The relationship between air permeability and the pressure differential was fitted well with power law curve. The study revealed that the coefficient c and exponent b in the power law equation had a strong correlation with porosity, which was chosen to characterize the airbag fabrics.
