Abstract: For resolving the problems of storage and reasonable application of a great deal of experimental data in the production of C/C composites by CVI, an experimental database platform for C/C composites was developed based on a structured query language server software as the basic database and VC+ + as the development platform. The connection between the platform and database was constructed with the ActiveX Data Objects, a data interface technique developed by Microsoft. The experimental data were divided into five classes, including process methods, process analysis, property analysis, microstucture analysis, and anti-oxidation coating and its efficacy. The CVI simulation and optimization were performed by integrating this platform with the Matlab-engine technique, results of which can be used to shorten the C/C composite production time, to improve the efficiency, and to lower the cost.
