Modular irNDT Solution for Carbon Composites

Composite-Check Functionality

Composite-check System

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.

Composite-Check Features

  • Non‐contact irNDT

  • Works with cooled and uncooled IR Cameras

  • Compatible with multiple irNDT methods

  • Effective even on low emissivity targets
  • Modular hardware and software
  • Configurable for different geometries and materials

Composite-Check Benefits

Composite-Check helps users better understand the characteristics of a composite material to optimize product design, lifecycle, and performance.

NON-CONTACT DEFECT DETECTION

Active thermography reveals the most subtle flaws and defects that are visibly undetectable.

FLEXIBLE AND EXPANDABLE

Upgrade the system by adding excitation sources, irNDT methods, and higher performance IR cameras.

irNDT Made Easy

Complex analysis technology is simplified for dependable inspection results.

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

Composite-Check transient Method

Transient

Halogen light is used to create an extended heat excitation. Thermography analyzes the change in the thermal state of the target.

Composite-Check Flash Method

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.

Composite-Check Lcok-In Method

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.

Composite-Check Vibro Method

Vibro

Ultrasound is used to excite the specimen. Friction between vibrating cracks creates heat signatures that are measured by the infrared camera.
