The innovation in new composite structural materials allows for more lighter and more economical products. With the increased use of composite materials, it has become apparent that conventional non-destructive testing (NDT) methods are often impractical or unsuitable for tests of these materials. With ability to find discontinuities (both those introduced during the manufacturing process and those that result from use) in composite structures, Laser Shearography has become one of the primary methods used for non-destructive inspection of composites.
Impact damage is a serious damage mechanism in composite materials, which limits their performance and reliability. Impact damage can occur during in-service applications or as a result of h[…]LEARN MORE
A NDT method for a structure with stiff stainless steel skins and low-density foam cores was to be found. Disbonds down to 25 mm should be detected. The defects may be positioned between ski[…]LEARN MORE
Shearography systems give wide potentialities in non destructive inspection (NDI) in cases where other methods provide insufficient results. One of the typical demonstrations of these possib[…]LEARN MORE
By essence, a defect weakens the structural properties of a component. Its mechanical behavior under a load is consequently modified. This modification can be localized and of very little im[…]LEARN MORE
The demand for greater product quality in industry has created a need for better and faster techniques for nondestructive testing. Because traditional techniques such as ultrasonic and radio[…]LEARN MORE
Laser shearography as a non-destructive testing (NDT) method has been used in a production environment for composite structures for two decades and on a variety of aircraft, including the F-[…]LEARN MORE
