After debulking, the resin is allowed to be infused by the vacuum to completely wetout the reinforcements and eliminate all air voids in the laminate structure. High quality composite parts made from a wide range of fiber and resin combinations can be utilized to infuse laminates up to six inches thick.
Typical resins used are polyester, vinyl ester, and epoxy with many being UV cure initiated.
This process can routinely produce large 2,000 sq. This processes added benefits include eliminating weaker secondary bonds and reduced VOC emissions vs. current open molding processes. Pigmented gel coats provide the parts surface finish and often a hand lay-up skin laminate may be fabricated to allow fabricators to walk on gel coated surface while loading the dry reinforcement laminate ply schedule and vacuum bag.
