Non-Destructive Testing Methods of Composite Materials: A Review

Maha S. Hirmaz

Abstract: A wide range of testing techniques are usually applied in industry to different materials in order to determine their fitness for use. Testing of composite materials present a certain challenge as they are non-homogenous and anisotropic materials. This paper covers several non-destructive testing methods and the common defects that can occur accidentally in composite materials either during manufacturing processes or in the course of the normal service life of the component.

Keywords: visual testing, radiography, shearography, thermography, ultrasonic testing, delamination, debonding.
