Curing Simulation of Composites Autoclave Forming Based on COMPRO Model

有效利用热压罐技术来实现复合材料成型的关键在于选择合适的工艺参数和制定合理的工艺方案,虚拟热压罐工艺仿真可以有助于对固化过程进行预测,提高工艺设计效率,降低生产成本。本文介绍了热压罐工艺仿真软件COMPRO以及典型的固化过程分析模型(热化学模型、流动压实模型和应力变形模型)。最后给出了影响COMPRO数值模拟的关键参数及翼梁样件试验数据与数值模拟对比,COMPRO可以较为准确的预测固化工艺。

t The appropriate parameter and reasonable process of technics is the key for autoclave molding of composite. The technical simulation of virtual autoclave make for the prediction of curing process, and the improve- ment of technical efficiency and reduction of manufacture cost. The paper show a software of autoclave simulation： COMPRO, and the typical model of curing process analysis： thermochemical model, flow-compaction model and stress deformation model. At last, the key parameter effect on COMPRO analysis have been shown, and a conclusion about accuracy of COMPRO analysis can be clone through the comparison between the data of spar prototype and COMPRO simulation.
