Summary

Our model for forced-flow/thermal-gradient chemical vapor infiltration (FCVI) provides a tool for process optimization and identifies effective sensors for run-time process monitoring and control For complex component geometry, the model allows one to design infiltration hardware and to select optimum process conditions for full densification. The model predicts that temperature measurement at points external to the component can provide an effective monitor of densification, while pressure is sensitive only to the final stages of the process. Run-time process monitoring and real-time model simulation of the process will allow feed-forward process control strategies and high reliability in composite fabrication.
