Resin Infusion. Benefits of The Infusion ProcessWhat Are The Limitations of Infusion?Other Names For Resin Infusion and Related Vacuum ProcessesCritical Elements of The Infusion ProcessLow investment cost Typically little more investment than that required to make composite parts using hand layup in open mouldsCapable of producing minimum weight high performance laminates with properties comparable to those of laminates produced by more expensive processes such as autoclave cured prepregInfusion allows the reinforcement materials to be handled dry This avoids the need for laminators to have contact with the resin significantly reducing workforce exposure to the resin AllergicThe process is carried out within a “closed” system that is within the void between a sealed bag and a mould or between 2 sealed moulds Hence there is minimal exposure of the uncured resin to t Infusion is a relatively slow manufacturing process It is usually not worth considering for applications requiring high production rates where another manufacturing solution is feasibleFor oneoff or large parts where multipleuse flexible films or top moulds are not practical or are prohibitively expensive the process can result in considerable waste (vacuum bag film resin tu Double (flexible) bag infusion A process where one vacuum level is applied to the reinforcement positioned between the mould and an inner flexible bag and a second vacuum level (usually a higherDVB process In the NASA developed double vacuum bag process a rigid perforated shell is interposed between 2 flexible bags Separately controllable levels of vacuum may be applied to the inner bCAPRI process Controlled Atmospheric Pressure Resin Infusion This is a version of infusion patented by Boeing Aircraft CoClosed moulding This is a general term covering a wide range of composite manufacturing processes conducted within some form of enclosed space eg between a rigid mould and a flexible film or A stack of DRY material(s) to be laminated is placed in a LEAKTIGHT mouldA LEAKTIGHT flexible film (commonly known as a vacuum bag) is placed over the laminate and SEALED to the mould beyond the perimeter of the laminate Where multiples of the same part are to be madA minimum of two connections are made to the bag one to permit air to be removed from the cavity between the bag and the mould and the other to allow liquid resin to enterWith the resin entry line temporarily CLOSED the cavity between the bag and the mould is evacuated by a vacuum pump The level of vacuum necessary will vary depending on the permeability of the m.
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.
Intoduction to the resin infusion (or vacuum infusion) process
Resin infusion is a sophisticated technique for manufacturing high performance void free composites even on large or complicated moulds.

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”.

Resin infusion is a composite moulding process whereby the liquid resin is drawn a stack of dry fabrics by the aid of vacuum pressure and in doing so impregnates the laminate We have applied resin infusion techniques for a wide variety of composite parts and tooling where it suits the process.
