Collection of process data using in-situ sensors

摘要

A system is provided for collecting data during vacuum molding of a composite part using a mold including an air tight, flexible membrane (26) sealed to a tool (24). The system comprises a plurality of MEMS sensors (30) 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.
