Abstract: Porosity causing gas-based defects are detected, located, identified, and/or characterized by the use of defect information generated from gas flow data corresponding to gas flow characteristics measured by one or more sensors on a composite part processing piece such as a mold or membrane used during a composite manufacturing process. The defect information is generated using techniques including one or more of profiling the gas flow data, fingerprinting, line leak detection, analytical triangulation.
