Vacuum Epoxy Resin Infusion Suit Kit For Carbon Fiber
Product Description
Vacuum resin infusion is a sophisticated technique for manufacturing high performance, void free composites even on large or complicated moulds. The process is ideally suited to the manufacture of carbon fibre composites and is widely used by professional manufacturers for the production of carbon fibre body panels such as bonnets and by marine manufacturers for the production of boat hulls.
In resin infusion, reinforcement is laid into the mould ‘dry’, i.e. without any resin, and then enclosed in a specially configured stack of bagging materials (such as peel ply, infusion mesh and bagging film) before being subjected to vacuum pressure using a composites vacuum pump. Once all the air has been removed from the bag and the reinforcement has been fully compressed under this pressure, liquid epoxy resin (mixed with hardener) is introduced to the reinforcement through a pipe which then infuses through the reinforcement under the vacuum pressure. Once the resin has fully infused through the reinforcement, the supply of resin is cut off (using a pipe clamp) and the resin is left to cure, still under vacuum pressure

Let’s dive deeper into what materials are used in vacuum bagging and how to use those materials to achieve a great composite part.The materials and how to use them will be described in the order they should be put down on the mold or laminate.
Sealant tapeLay down a layer of sealant tape around the perimeter of the part, leaving some space between it and the laminate. The area where the tape is put down should be clean and free of epoxy residue and stray fibers. Sealant tape is also commonly referred to as tacky tape or mastic sealant.
Release fabric
Release fabric should be laid directly on top of the wet laminate. Release fabric leaves a textured finish when it is removed, reducing the need for surface prep before secondary bonding. Release fabric is commonly referred to as peel ply. The most common types of peel ply are made out of nylon or polyester fibers. Some peel ply is coated with release agents.
Release film
Perforated release film is a thin plastic with small holes that control how the excess epoxy moves from the part to the breather fabric. This is an optional layer in the vacuum bagging process.
Breather fabric
The function of the breather fabric is really two-fold. As vacuum pressure consolidates the laminate, the squeezed-out epoxy goes through the peel ply (and the release film if you are using it) and is absorbed by the breather fabric. Because of its open structure, air flows easily through breather fabric allowing the air to be evacuated from the consolidated laminate. Breather fabric is also referred to as “baby blanket.”
Product Advantage
Resin infusion, when done correctly, can produce parts of incredible strength and quality of appearance. The combination of vacuum pressure along with carefully placed vacuum consumables (such as peel-ply and infusion mesh) mean that the finished composite will
have absorbed resin at the optimum resin-to-reinforcement ratio, avoiding resin-rich composites or variations in performance inevitable with traditional wet-lay manufacture.
have absorbed resin at the optimum resin-to-reinforcement ratio, avoiding resin-rich composites or variations in performance inevitable with traditional wet-lay manufacture.
The resin infusion process also eliminates some of the problems that can blight wet-lay composites, such as air voids (caused where the reinforcement has bridged around tight corners) and tiny air bubbles caused by air trapped within the laminate.
The quality of epoxy ‘infusion resins’ means that resin infused parts can be made with
strength to weight ratios that can rival parts made using pre-impregnated (pre-preg) reinforcement systems.
