Resin infusion is the process whereby resin is drawn into a dry laminate whilst it is held under vacuum against a rigid mould by a sealed flexible membrane. The most commonly used membrane consists of a disposable film (vacuum bag) and this film is sealed against the mould edges using a sealant tape.
What is resin film infusion process?
Unlike RTM, the resin film infusion (RFI) process requires just one male, or female, mould of the desired shape [14]. Dry fabrics are laid up interleaved with layers of pre-catalyzed semisolid resin film supplied on a release paper. Then, the lay-up is vacuum bagged to remove air through the dry fabrics.
How long does resin infusion take?
Once the part is fully infused, the resin and vacuum tubes are clamped off and the catch pot/vacuum system can be removed. The part should remain under full vacuum until the resin has cured. Depending on the resin system this can take 3-12 hours.
What is epoxy infusion?
Resin Infusion is a process by which 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”.
What is infusion molding?
The Vacuum Infusion Process (VIP) is a technique that uses vacuum pressure to drive resin into a laminate. Dry materials are laid into the mold and the vacuum is applied before resin is introduced. Once a complete vacuum is achieved, resin is literally sucked into the laminate via carefully placed tubing.
What are the 3 types of resin?
There are three main types of Resins used today for use with Carbon Fiber, Fiberglass, and Aramid (Kevlar). These are Epoxy, Vinylester, Polyester Resins. Each has different characteristics and associated costs.
What are the three 3 types of commonly used resin?
There are three widely used resin types: polyester, vinyl ester, and epoxy.
Do you need to wear a mask when working with resin?
When sanding, grinding, or drilling resin, wear a particle mask or a NIOSH respirator approved for dust. It is important not to inhale the resin dust, which could cause an allergic reaction.
How long does resin take to heal?
Epoxy curing time is typically 7-days. Of course, there are variations, but if you want a rule of thumb, 1-week is your answer. While it takes 7-days for the epoxy to cure, your floor may be dry enough to walk on after 12-hours or so, and ready for light use after 24-hours.
How long before resin fully cures?

How do you apply resin to film?
Quote from video: Don't fill it all the way up to the top because you are going to need to leave a little bit of gap at the top for more resin.
What is resin infusion under flexible tooling?
Resin Infusion under Flexible Tooling (RIFT): a review
RIFT is a variant of vacuum-driven RTM in which one of the solid tool faces is replaced by a flexible polymeric film. The process is known by several acronyms—in this paper it is referred to as RIFT (Resin Infusion under Flexible Tooling).
What is resin in injection molding?
It is a soft plastic resin, making it easy to shape into different products using the plastic injection molding technique. The ability to withstand high-temperature levels, coupled with high tensile strength, gives this resin application in cable insulations, sports gear, and electrical tools.
