Infusion Material. 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.

Fabrics for Infusion Hexcel has developed a full range of fabrics specifically for customers who use infusion In addition to modifying the construction of our standard fabrics to enable higher and more consistent infusion rates our range also encompasses fabrics that include a raft of different infusion cores within the structure including polypropylene polyester natural fiber and glass fabrics.

Vacuum Infusion Process: StepbyStep Guide for Resin

The most commonly used IV bags and infusion sets are made from polyvinyl chloride (PVC) The main reasons for using PVCbased materials are their high strength and flexibility (if plasticized) transparency ease of sealing good resistance to sterilization procedures and relatively low cost (Smith et al 1989 ).

The best infusion resins are epoxy (including the infusion resin that comes with this kit) therefore it is important that the surface of the mould that will be used for infusion is also made from epoxy either an epoxy tooling gel coat or just epoxy resin used as a surface layer.

The Vacuum Infusion Process (VIP) is a technique that uses vacuum pressure to drive resin into a laminate Materials are laid dry into a mold and the vacuum is applied before resin is introduced The resin is infused into the mold cavity to wet out the materials and core during the vacuum infusion Carbon fiber and fiberglass are mold materials commonly used for this process.
