Overview
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.

Fabrication methods 11/1/2007 Composites TechnologyThere are numerous methods for fabricating composite components. Some methods have been borrowed (injection molding, for example), but many were developed to meet specific design or manufacturing challenges. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application.
