Airbag fabrics and seat belts
We have more than 20 years of proven experience in passive safety. This has allowed us to develop specific methods for characterizing airbag and seatbelt fabrics aimed at improving the predictivity in the simulation of restraint systems. These proprietary methods satisfy the most demanding requirements of the automotive industry, having been developed in collaboration with German OEMs. Our clients in this field are leading companies in this sector.

Specific test methods
With the aim of feeding the simulation models, our experimental methods allow us to determine the mechanical and friction behavior of the fabric, as well as its permeability.
Our test portfolio includes among others:
- Uniaxial (based on EN ISO 13934), biaxial and picture-frame tests in quasi-static and dynamic conditions, with flexible configurations of charge / discharge cycles at real temperature (RT, high and low)
- Dynamic air permeability tests of the fabric under an improved method based on the ASTM D6476 standard at different temperatures (RT, high and low)
- Tests to determine the static and dynamic friction coefficient of the fabric according to the ASTM D1894 standard at real temperature (RT, high and low)

Specific analysis methods
Our methodologies include special instrumentation and post-processing techniques that accurately capture the actual behavior of the material. For this, strain is directly measured on the fabric and the mechanical behavior of the material and its dependence on the strain rate are analyzed by means of 3D surfaces.

Cards for simulation codes
From the experimental results we can generate highly predictive material cards to be used in simulation codes.
Safety belts
All these methods have been adapted for the testing of seat belts, providing an excellent characterization tool for this type of fabric.
