探讨敲击检测技术在复合材料无损检测中的应用

Discussion on the Application of the Knock Techniques on the Non-destructive Test

本文根据纤维增强复合材料的特性,列出了损伤的主要类型和产生原因;对适用于复合材料制品的无损检测敲击技术进行探讨;对敲击技术的基本原理、方法分类、适用范围进行介绍;对传统敲击法和数字敲击法进行比较;总结敲击法的未来发展状况。

The types and occurring reasons of defects were listed according to the characteristics of fibre reinforced composites . The knock detection in the non-destructive test applicapable to composite products were discussed in this paper. The basic principle, method classification and applicapable scope of knock techniques were introduced. The traditional knock and the digitknock were compared. The future development of the knock techniques were summarized.
