FAQs

What is vacuum resin infusion?

Vacuum resin infusion is a sophisticated composite manufacturing process that's employed to create high-strength, lightweight structures with superior finishes. Often used in industries that demand precision and durability—such as aerospace, automotive, marine, and wind energy—this technique involves the drawing of a liquid resin into a reinforcement material, like fiber cloth, using vacuum pressure.

What are the benefits of vacuum infusion?

• Improved Fiber-to-Resin Ratio: Vacuum infusion allows for a more controlled process where the resin-to-fiber ratio can be tightly managed, ensuring a uniform distribution of resin throughout the composite material.
• Higher Quality Parts: The low-pressure environment used in the vacuum infusion process can reduce the formation of voids and air pockets, resulting in stronger and more reliable parts.
• Reduced Emissions: This method minimizes emissions of volatile organic compounds (VOCs) because the resin is contained within the vacuum bag, making it more environmentally friendly than open molding processes.
• Material Savings: The vacuum infusion process tends to require less resin than hand lay-up processes, leading to reduced material costs and less waste.
• Weight Reduction: The optimal resin-to-fiber ratio achievable with vacuum infusion often results in lighter components, which is particularly advantageous in automotive, marine, and aerospace applications.
• Complex Geometries: Vacuum infusion is capable of producing complex shapes and large structures that might be difficult to achieve with traditional manufacturing methods.

How much resin is needed for vacuum infusion?

The resin calculation typically starts with knowing the area weight of the fiber reinforcement in grams per square meter (g/m²) and the total area to be infused in square meters (m²). The general rule of thumb is a resin-to-glass weight ratio ranging from 1:1 to 2:1, which means for every gram of fiber, one to two grams of resin are needed. The following factors should also be considered:

1. Laminate Thickness: The thickness of the fiber reinforcement dictates resin consumption. A thicker laminate will require more resin to saturate the fibers adequately.
2. Fiber Type and Weave: Different fibers and weaves hold varying amounts of resin. For example, a tightly woven fabric may require less resin than a loose weave, as there is less space between the fiber to fill.
3. Porosity of the Laminate: The porosity or the amount of void space in the material is another factor that can impact resin requirement. A more porous material will naturally soak up more resin.
4. Resin System: Resin systems can have vastly different viscosities. A low-viscosity resin will spread more easily, potentially reducing the amount needed. Additionally, the specific resin-to-hardener ratio must be strictly adhered to maintain material properties.
5. Additions and Core Materials: Incorporating cores or other materials into the laminate will alter the amount of resin needed. These materials can absorb resin or, conversely, displace an area that would otherwise be filled with resin.

How thick is a vacuum infusion?

Several factors during the infusion process can influence the thickness of the resultant composite, including fiber layup configuration, resin quantity, and compaction pressure. Our vacuum infusion supplies deliver superior results for your projects.
