摘要
针对复合材料热压罐工艺中最易出现的分层缺陷,提出并建立了复合材料构件分层缺陷的概率分析方法与群子理论模型,并分别利用这两种方法对不同构形复合材料构件分层缺陷进行了评价,求得了不同构形复合材料构件分层相对可接受率与反映分层面积倾向性的群子参数。结果表明,两种统计方法对分层缺陷的评价结果一致性较好,构形复杂的复合材料构件产生大分层的倾向性增大且分层相对可接受率较低。
Aimed to that the of delamination is easily appeared in composites during autoclave process,this study focuses on proposing and developing the probabilistic analysis method and sub-cluster theory model of delamination for composite components in order to evaluate quantitatively the process quality of composite components with different shape.Some quantitative results of the relative acceptable rate of detamination and the sub-cluster parameters reflecting the tendency of delamination area are obtained.The results indicate that a good agreement is observed between these two statistical methods for evaluating process quality of composite components.The more complicated shape of composite components,the higher tendency of the large delamination area appearance and the lower relative acceptable rate of delamination.The results provide important theoretical analysis methods for evaluating process quality of composite components.
