Breather Fabric
Non-Woven Aerovac Breather Fabric is Tailored to Meet Your Requirements
Breather fabric is a 100% non-woven polyester or nylon fabric that is designed to allow airflow throughout the vacuum bagging process as well as bleed out an excess resin in a composite part. It allows great conformity around a composite part while under vacuum or autoclave pressure. Aerovac manufactures breather fabric in standard roll formats, slit widths, or cut shapes tailored to meet your requirements.
Our high-quality breather fabrics allow airflow throughout the vacuum bagging process as well as bleed out excess resin in a composite part, allowing great conformity around a composite part under vacuum pressure.
Aerovac Breather Fabrics are available through Composites One in North America, or globally through the Aerovac Distributor Network.
