Composite-Check
Modular irNDT Solution for Carbon Composites
Composite-Check Functionality
Composite‐Check is a modular infrared non‐destructive testing (irNDT) system that uses active thermography for the reliable detection of delaminations, impact damages, “near side” defects, water inclusions, debondings, and other defects in composite materials.
The system achieves precise measurements and is ideal for inspecting composite materials like carbonfiber reinforced plastics (CRP), glassfiber reinforced plastics (GRP), carbonfiber reinforced ceramics (CFRC), glassfiber reinforced aluminum laminate (GLARE), and honeycombs.
Composite‐Check accommodates a wide range of irNDT measurement methods to include: Flash‐Thermography, Lock‐In Thermography, Transient Thermography, and Vibro‐Thermography. It also works with multiple excitation sources and with cooled or uncooled infrared camera systems.
How does it work?
Composite‐Check works utilizing active thermography. A heat source provides the inspected material with a thermal excitation. The flow of thermal energy through the material has a direct effect on surface temperatures. The surface temperature is recorded over a certain time period with an infrared camera and analyzed by the irNDT software.
The software produces an image that provides information about the internal structure of the material

Composite-Check – irNDT Methods
Transient
Halogen light is used to create an extended heat excitation. Thermography analyzes the change in the thermal state of the target.
Flash
Xenon light provides a short and intense excitation that is analyzed with thermography. Is well suited for materials with high thermal conductivity and shallow defects.
Lock-In
A periodical excitation source is synchronized with the IR camera. The software generates an amplitude and phase image to indicate the location and nature of the defect.
Vibro
Ultrasound is used to excite the specimen. Friction between vibrating cracks creates heat signatures that are measured by the infrared camera.
