Resin infusion FLOW MEDIA for the production of big-sized composites elements, such as wind baldes.


TENAX manufactures smart solutions to help the infusion in composite elements production. Dual-flat rhomboidal meshes show a great effectiveness if used as flow media in the vacuum assisted resin infusion (VARI).
Raw material, mesh size, thickness and width can be customized according to the temperature and chemical compatibility required by the process.


The usual layer-configuration of a composites mold includes the following items: the reinforcement fibers, the “peel ply” (to help the adhesion and the after-work separation), the flow media mesh and the bagging film with the nozzle to inject the resin. Once the air inside the bag is sucked, the epoxy constituent can flow inside. Thanks to the channels created by the grid, the fluid manages to reach any field of the composite surface with no risk of inconsistency or voids in the final product.


The use of this kind of net allows the uniform distribution of mechanical and geometrical features throughout the mold and maintains the flow speed under control.

The so-manufactured composites are suitable as wind blades, light plane wings, boat hulls and any other applications, which reaches high mechanical stress rates.
