Spray up is a traditional open-mold process in which chopped fiber and thermoset resin is sprayed on to a mold, consolidated and then cured. This process dominated composites for many years, but is gradually being replaced by closed-mold processes like RTM.
KraussMaffei (Hall 6, F61) is featuring several composites manufacturing technologies, covering wet molding, pultrusion, long fiber injection and overmolding.
