SHEAROGRAPHY - A FAST AND FLEXIBLE NDI TECHNIQUE FOR COMPOSITE MATERIALS NEW APPLICATIONS IN VARIOUS INDUSTRIES

摘要

Modern hi-tech products today widely are made of composite materials, which are specifically designed for the purpose of their application. Other than a precise knowledge of the characteristics of these materials, which often are anisotropic, quality control is of the essence. As said components, e.g. in aerospace, aircraft, or also boat industry and other thriving industries such as wind power industry are safety relevant, and also of great economic value, rapid defect recognition has to be carried out in production as well as in maintenance. Shearography is a full field inspection technique, which is specifically suited to do fast defect detection. It is widely accepted as a reliable and fast inspection method especially designed for modern composite material. Latest generation of Shearography technique and software are presented and the potential is outlined. Different challenges are presented in production control and in maintenance, specifically in Aircraft and Wind Energy.
