Diabreaker: control the resin flow and ensure the safety of your vacuum infusions

What is a Diabreaker composite infusion?

The Diabreaker is an accessory used in vacuum infusion for the production of composite parts.

Its role is to create a vacuum while slowing the flow of resin. It allows you to:

• Maintain a good level of vacuum throughout the infusion
• Reduce the risk of dry patches
• Limit resin consumption

Using it greatly simplifies the infusion process and minimises the risk of waste.

What is a Diabreaker used for?

In an infusion process, the resin naturally tends to follow preferential paths. This can result in:

• dry areas
• excessive resin consumption
• vacuum loss
• structural defects

The Diabreaker acts as a flow regulator:

• it locally inhibits the resin
• It ensures uniform impregnation
• It improves the final quality
• It secures complex areas

Why use a Diabreaker in a vacuum infusion system?

Resin front control

Helps prevent the machine from moving too fast and out of control

Defect reduction

Minimises air bubbles, dry spots and incomplete saturation

Optimising resin consumption

More even distribution = less material loss

Securing complex parts

Essential for technical geometries or large surfaces

How does a Diabreaker work?

The system works by using a combination of materials that allow for a gradual and controlled slowing of the resin flow, without sudden blockages.

Integrated hose: enables vacuum and/or flow control

Nonwoven polyester felt: provides controlled flow resistance

Release film: prevents sticking and controls resin flow

Where should a Diabreaker be installed?

To ensure uniform impregnation rates throughout the entire part, the Diabreaker is typically positioned:

• at the end of the play
• in areas at risk of split path
• near the vacuum outlets
• in thick or complex areas

When should you use a Diabreaker?

The use of a Diabreaker is recommended in the following cases:

• large parts
• complex or multi-thickness shapes
• Critical processes in aviation, marine engineering and wind power
• need for high structural quality
• infusion using low-viscosity resin (fast flow)

Diabreaker vs. other flow control solutions

How can you avoid dry patches when infusing?

How can you avoid dry spots when brewing tea?

By slowing the flow with a Diabreaker to allow for complete saturation

How do you monitor the resin front?

By positioning braking zones such as the Diabreaker

Why does my resin come out of the vacuum too quickly?

Lack of regulation → Adding a Diabreaker is recommended

A must-have for perfecting your infusions

The Diabreaker is a strategic tool for composite manufacturers. It does more than simply guide the flow; it allows for precise control of the flow, ensuring reliable, consistent and defect-free parts.
