Breather polyester nonwoven fabric for vacuum infusion and bagging
Breather polyester nonwoven fabric is an essential auxiliary material used in the processes ofvacuum resin infusion andvacuum bagging. Its primary function is to drain air and excess resin and to evenly distribute the vacuum across the entire surface of the laminate.
Thanks to its spatial structure, the Breather allows free airflow inside the vacuum bag, enabling the production of composites with high mechanical strength, low air void content, and excellent surface quality.
Applications
Breather nonwoven fabric is used in:
-
vacuum infusion of epoxy resins,
-
infusion of polyester and vinylester resins,
-
vacuum bagging,
-
production of fiberglass components,
-
production of carbon fiber components,
-
boat and yacht construction,
-
aerospace industry,
-
automotive industry,
-
production of composite elements with complex shapes.
Key advantages
-
effective air and excess resin drainage,
-
even distribution of vacuum across the laminate surface,
-
improvement of quality and uniformity of the composite,
-
reduction of the risk of air void formation,
-
flexible structure adapting to complex forms,
-
possibility of using one or several layers depending on process needs.

-
easy adaptation to irregular surfaces.
Important information
Breather nonwoven fabricdoes not have separating properties, therefore during the infusion or lamination process it should be used together withperforated film orPeel Ply fabric, which prevent permanent bonding of the nonwoven fabric to the laminate.
Why is it worth using Breather nonwoven fabric?
Proper distribution of vacuum is crucial for the quality of the infusion process. The Breather nonwoven fabric ensures effective venting of the system and drainage of excess resin, resulting in better fiber saturation, higher mechanical strength, and an aesthetic finish of the final component.
Breather polyester nonwoven fabric is a fundamental consumable material in composite technology, which increases the efficiency of the infusion process and allows for professional results in both industrial production and hobby applications.
Available weights of Breather nonwoven fabric
Breather polyester nonwoven fabric is available in several weights, allowing optimal adjustment of the material to the type of process and size of the composite element being produced.
| Weight | Application |
|---|---|
| 150 g/m² | Standard vacuum infusion processes and vacuum bagging, small and medium composite elements. |
| 250 g/m² | Versatile use for larger laminates and processes requiring better air drainage and excess resin removal. |
| 300 g/m² | Large composite elements and demanding industrial processes where maximum vacuum distribution and effective resin drainage are necessary. |
The availability of different weights allows for selecting Breather nonwoven fabric for specific technological processes, ensuring optimal air flow, even distribution of vacuum, and the highest quality of the finished laminate.
