Breathable felt/ Vacuum Bagging breather

A non-woven fabric designed to allow air and gases to pass through while filtering or absorbing liquids and fine particles.

In composites manufacturing, it is often used as a breather/bleeder layer in vacuum bagging to ensure uniform resin flow and air removal.

The breathable structure prevents voids and dry spots in laminates, producing high-quality, void-free carbon fiber or fiberglass parts.

It is compatible with epoxy, polyester, and vinyl ester resins, making it essential for aerospace, marine, and medical component fabrication.
