VACUUM INFUSION:

 Vacuum Infusion, also called resin infusion, utilizes a vacuum bag to debulk or compact an FRP laminate sequence of fiberglass reinforcements and/or core materials laid in a female mold.  After debulking, a flowable resin is infused by vacuum to completely wetout the fiberglass reinforcements and eliminate all entrapped air voids in the laminate structure.  High quality composite parts up to 6" thick can be constructed using the vacuum infusion process.  Typically, flowable isophthalic, vinylester and/or polyester resins  are used in the vacuum infusion fabrication process.  Since the vacuum infusion process eliminates the need for secondary bonding, a vacuum infused FRP part is stronger, lighter and less expensive than a comparable open molding FRP part.
