【Abstract】 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.更多还原
