Abstract:
The vehicle airbags are safety systems used to cushion the driver or passenger
during a collision and reduce bodily injuries. Airbags are typically made from
woven fabric, which may be coated or uncoated fabric. In this research nylon 66
fabric was Coated with composite of polyvinyl alcohol (PVA) and different
concentration of silica (SiO2) nanoparticles. The fabrics were characterized by
different instruments such as Scanning Electron Microscopy (SEM), Fourier
Transform Infrared (FTIR) Spectroscopy, Differential Scanning Calorimeter
(DSC),Thermogravimetric Analysis (TGA), Water Contact Angle (WCA), Tensile
Strength Tester and Airpermeability Tester. Nylon 66 fabric was coated with PVA
and higher concentration of silica nanoparticles has a thin layer thickness rechead
to (0.009mm). Moreover, the final dry weight of the coating (PVA/SiO2) material
taken by the nylon 66 fabric is 0.4 gram per square meter. The thermal properties
of nylon 66 coated with PVA/SiO2 nanoparticles has been improved, including
better mechanical properties according to commercial guidelines airbag (FMVSS).
Nylon 66 fabric coated with PVA/SiO2 nanoparticles demonstrated the a
hydrophobicity property. The airpermeability has decreased by increasing the
amount of silica nanoparticles in the composite material.
