Adaptive Process Control of Compression Molded Composites

摘要

Much work has been accomplished in the area of in-process monitoring and/or real-time control of polymer matrix composites (PMC) processing, from sensor development to artificial intelligence. However, little success has been experienced in integrating this type of technology into a robust cost effective system. Through a cooperative effort between Allen-Bradley, Erie Press Systems, the National Center for Manufacturing Sciences and United Technologies, Pratt and Whitney, an adaptive process control system for compression molded composites is presented. The quality manufacture of Pratt and Whitney's PMC Fan Exit Guide Vanes (FEGVs) depend on the chemical state of the raw material and the proper application of heat and pressure during the cure cycle process.
