How can air bubbles be avoided during infusion ?

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

What vacuum pressure should be applied ?

A high vacuum level is generally sought to properly compact the fibers, while remaining compatible with the mold and the materials used. The setting depends on the type of part and resin.

Can infusion be used for large parts?

Yes, infusion is particularly well suited for large composite parts, such as boat hulls or structural panels, thanks to its ability to impregnate large surfaces uniformly.

What is the difference between infusion and RTM?

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.

Does vacuum improve mechanical properties ?

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

Is training required to get started with infusion ?

No extensive training is required, but a good understanding of the process and the products used is essential. Technical support helps ensure the success of initial projects.

Can you receive support in selecting vacuum bagging products?

Yes, Sicomin solutions are developed with technical support to help select the most suitable product combinations for each project and process.

Does vacuum processing help reduce resin consumption?

Yes, infusion optimizes the fiber-to-resin ratio, which helps reduce resin consumption while improving the final performance of the part.

Can infusion and post-curing be combined ?

Yes, post-curing after infusion helps increase the thermal and mechanical performance of epoxy resins, especially for demanding applications.

Is vacuum infusion suitable for technical parts ?

Yes, it is one of the most commonly used processes for manufacturing technical composite parts requiring reliability, repeatability, and a high level of performance.

What is vacuum bagging in composites ?

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.

À quoi sert la mise sous vide avec la résine époxy ?

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.

Quelle est la différence entre stratification manuelle et infusion ?

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.

Why use epoxy resin for infusion ?

Epoxy resin is ideal for infusion due to its low viscosity, excellent fiber wet-out, and high mechanical performance, making it suitable for technical parts.

What are the advantages of vacuum infusion ?

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

Which products are required for vacuum bagging ?

A vacuum bagging system generally includes a vacuum pump, vacuum film, peel ply, flow media, hoses, fittings, and an epoxy resin compatible with infusion.

Is vacuum bagging reserved for professionals ?

No, vacuum bagging is accessible to individuals and craftsmen. With the right products and an appropriate method, it is possible to achieve excellent results even for a first project.

In which industries is vacuum infusion used ?

Infusion is used in aerospace, automotive, marine, defense, industrial, and sports and leisure sectors to manufacture high-performance composite parts.

Which epoxy resin should be chosen for infusion ?

It is recommended to use an epoxy resin specifically formulated for infusion, with low viscosity and sufficient working time to fully impregnate the fibers.

Can all composite fabrics be infused ?

Yes, infusion is compatible with glass, carbon, aramid, and hybrid fabrics, provided that the consumables and infusion strategy are adapted to the type of fiber.
