为了解决C/C复合材料CVI(Chemical Vapor Infiltration,CVI)制备工艺中大量实验数据的有效存储及合理利用问题,设计开发了C/C复合材料实验数据库系统平台,利用SQL Server作后台数据仓库,VC++作平台系统开发,以ADO对象作数据库连接技术,从工艺方法、性能分析、组织结构等方面对实验数据整理分类,并利用Matlab引擎技术整合CVI工艺优化仿真程序,对材料制备工艺进行模拟和优化,该系统平台有助于缩短C/C复合材料制备周期,提高生产效率,降低生产成本。
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.
