What is a common material used for headliners in vehicles?

Headliners in vehicles are typically made from fabric due to several key reasons. Fabric is lightweight, which helps to reduce the overall weight of the vehicle, contributing to better fuel efficiency. It also provides a level of comfort and aesthetic appeal, as it can be easily customized in terms of texture and color to suit the interior design of the vehicle. Additionally, fabric materials can help with sound absorption, creating a quieter cabin environment, and can be manufactured with various fire-resistant properties to ensure safety standards are met.

While vinyl is another material sometimes used in headliners, it is more commonly associated with other interior components or as an option over fabric in certain models. Wood is impractical for a headliner due to its weight and rigidity, making it unsuitable for the flexible requirements of this component. Glass, on the other hand, is not used at all for headliners, as it does not have the necessary properties for insulation or ease of installation and maintenance within the vehicle's interior. This makes fabric the predominant choice for headliner construction in modern automobiles.
