The technique of vacuum drawing resin into a dry fiber laminate in a one-sided mold is known as resin infusion. Over the top, a rigid or flexible film membrane is applied and sealed around the mold periphery. Resin infusion is categorized as a "Closed Mold Process."

The advantages of resin infusion over non-vacuum bag curing of composite laminates include:

Better fiber to Resin ratio
Stronger laminate
Low void content
Reduce operator exposure to harmful emissions
Reduce resin usage due to pre-compacted fabric
Faster Ply lay-up

Resin Infusion is a process by which a vacuum draws resin into a dry fiber laminate in a one-sided mold. A rigid or flexible film membrane is placed over the top and sealed around the mold periphery. Resin infusion is considered a “Closed Mold Process”.

The benefits of resin infusion when compared to non-vacuum bag curing of composite laminates include: better fiber to resin ratio, stronger laminate, low void content, lower chance of operator being exposed to harmful emissions, reduced resin usage due to pre-compacted fabric, and faster ply lay-up.

Airtech offers a wide range of high-quality resin infusion products, including: tackifiers, flow media, flow lines, infusion connectors, semi-permeable membranes, infusion resins, and unique solutions to reduce waste and increase cycles times when infusing. Airtech also features a Resin Infusion Starter Kit with all the needed items to start infusing today!
