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。
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.
