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.
A proven alternative to open molding of big parts.
Composite Spray Molding enables volume production of fiber-reinforced polyurethane sandwich structures for auto interiors. Are Class A exterior parts next?Fabrication methods CompositesWorld
There 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.External mix gun CompositesWorld
