Vacuum parts and infusion

Vacuum bagging and infusion for epoxy resin enable the production of lightweight, strong, and homogeneous composites. Using suitable consumables (peel ply, breather fabrics, films, infusion meshes), these processes ensure optimal impregnation, an excellent resin-to-fiber ratio, and a high-quality finish. Widely used in marine, industrial, sports, and aerospace applications. ... Read more

Our answers to your most frequently asked questions

What is vacuum bagging in composites ? À quoi sert la mise sous vide avec la résine époxy ? Quelle est la différence entre stratification manuelle et infusion ? What are the advantages of vacuum infusion ? How can air bubbles be avoided during infusion ? What is the difference between infusion and RTM? Does vacuum improve mechanical properties ?

Vacuum bagging is a process that consists of applying negative air pressure to a laminate in order to compact the fibers, remove air, and optimize epoxy resin impregnation to obtain high-quality composite parts.

Elle permet d’améliorer la résistance mécanique, la légèreté et la qualité de surface des pièces composites en réduisant les bulles d’air et l’excès de résine.

La stratification manuelle consiste à appliquer la résine directement sur les tissus, tandis que l’infusion fait circuler la résine époxy sous vide à travers les fibres sèches, offrant un meilleur contrôle et une qualité supérieure.

Infusion makes it possible to produce lighter, stronger parts with better repeatability and consistent quality, even for large components.

Good vacuum circuit sealing, proper degassing, and appropriate placement of flow media help effectively limit air bubbles.

Infusion uses an open mold sealed with a vacuum film, whereas RTM is performed in a closed mold. Infusion is more flexible and accessible for many projects.

Yes, vacuum bagging increases the fiber content, reduces internal defects, and significantly improves the mechanical performance of composite parts.
