中文摘要：

为有效积累和利用复合材料维修知识以提高维修质量和效率，提出一种基于本体的复合材料挖补修理知识建模方法。首先深入分析了复合材料挖补修理过程并归纳出该过程中蕴含知识的组成；然后分析了本体与复合材料挖补修理知识建模的关系，进而提出基于本体的知识建模方法；在此基础上构建了复合材料结构挖补修理领域本体框架，并分别对本体的类、属性、关系和实例进行定义，最后利用关系数据库实现了知识本体的形式化描述从而完成了知识建模。实例证明了方法的有效性。

英文摘要：

The maintenance knowledge of composite material component can improve the maintenance quality and e fwiency. To accumulate and apply the knowledge, scarf repair knowledge modeling method for composite based on ontology is presented. Firstly, the scarf repair process was analyzed and the knowledge contained in this process was summarized. Then, the relationship between ontology and scarf repair knowledge modeling was studied and the knowledge modeling method based on the ontology was proposed. On this basis, the domain ontology framework was constructed and the class with attributes, relationships and instances were defined. Finally, the relational database was used to realize the formal representation of the ontology. The experimental results show that the proposed method is effective.
