Beschreibung
Zusammenfassung:	A resin barrier device for connection in a vacuum line, for use in resin infusion during composite manufacture, includes a housing having an inlet port for connection to a resin source and an outlet port for connection to a vacuum source. A flow path extends between the inlet and outlet ports. A gas-permeable membrane is disposed across the flow path to prevent resin from flowing to the vacuum pump. A gasket supports the membrane and is adapted to prevent resin leakage. A method of infusing a preform with a resin also is provided.
