中文摘要：

针对C／C复合材料各仿真子系统相互独立，不能整体上反映C／C复合材料的工艺、组织和性能之间相互关系的现状，提出了在C／C复合材料数据库上实现制备工艺、组织分析与性能预测的综合模拟。运用C／C复合材料、数据库、软件编程以及计算机仿真等多个学科领域的知识，以C／C复合材料实验数据库为数据引擎，基于VC＋＋开发平台建立C／C复合材料工艺与组织分析综合仿真系统。并构建了力学性能预测仿真架构。系统在统一数据库基础上，将热梯度CVI（化学气相渗透）工艺仿真、组织分析和力学性能预测综合为一体，并实现了热梯度CVI工艺仿真和组织分析功能，对C／C复合材料一体化仿真的研究具有重要指导意义。

英文摘要：

The simulation systems of carbon-carbon composite materials are independent. The process, microstructure and properties of C/C composites have no relationship. To solve the problem, the comprehensive simulation of CVI （Chemical vapor infiltration） , microstructure-analysis and properties-forecast of C/C composite materials was investigated based the experimental database. Many disciplines such as C/C composite materials,database,software programming and computer simulation were used. The simulation system that utilized experimental database of C/C composite materials as data engine was established by VC ＋ ＋ platform, and the framework about properties- forecast was built. The paper united TCVI, microstructure-analysis and properties-forecast as one system. The sys- tem achieves TCVI process simulation and microstructure-analysis. It has important guiding significance for researc- hing integrated simulation of C/C composite materials.
