Abstract

Nowadays, composite materials are more and more used in advanced structural applications, especially in the aeronautic and aerospace field when having both lightweight and resistant structures is a great challenge. This report examines the different kinds of defects in composite laminates which can be used in the aerospace field. The goal of this report is to determine all the defects that can occur in a composite material and to define the different non-destructive methods enabling their detection. After the determination of the defects that can occur in a composite material, a study has been made to choose the most preferable non-destructive method to detect delamination. The ultrasonic inspection method seems to be the most adequate method but thermography and shearography can be used under some particular conditions.
