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 mould 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.

Detection, monitoring, and management of gas presence, gas flow and gas leaks in composites manufacturing

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.

A system is provided for collecting data during vacuum molding of a composite part using a mold including an air tight, flexible membrane sealed to a tool. The system comprises a plurality of MEMS sensors coupled with the interior of the mold at different locations over the part. Each of the sensors produces signals related to a process parameter, such as pressure within the bag, that is sensed at the location of the sensor.
