Abstract: The invention describes an advanced mixing and metering technology with online analytics for a supply of formulated liquid thermosetting resins into an open or closed mold. The application addresses where a precise control of the composition of formulated components is required. Composite structures used in primary and secondary structural aerospace applications manufactured in Infusion or RTM processes are possible examples.
