Which statement best describes the powders used in airbags?

• A. To color the fabric.
• B. To perfume the interior.
• C. Lubrication.
• D. To reinforce the fabric.

Answer: (C)

Powders inside airbags serve as a dry lubricant between the fabric layers as the bag deploys. This coating reduces friction and prevents the fabric from sticking, snagging, or tearing as it unfurls and inflates rapidly. By easing the movement of the material, the bag can deploy smoothly and fill properly to cushion occupants. The other ideas—coloring the fabric, perfuming the interior, or reinforcing the fabric—do not impact deployment, whereas the powder’s main role is to facilitate a smooth, reliable expansion.
