Testing of the Dynamic Permeability and Deformation of Airbag Fabrics

Abstract

Three different types of PA66 uncoated airbag fabrics are selected, dynamic permeability and deformation are measured by dynamic air permeability testing measurement. Average dynamic air permeability and exponent of dynamic air permeability are used to describe dynamic permeability; bulging curve and biaxial strain/stress curve are used to describe deformation. Testing results showed great useful to airbag products.
