Composite Material Inspection

Composite material: carbon fibers
Composite material: carbon fibers

EasyInspect for composite material inspection is a complete solution for the detection of defects in carbon and glass fiber materials for highly demanding applications. It examines 100% of the composite material surface for local defects. 

EasyMeasure continuously monitors the complete material width for variations in  material homogeneity, grammage and mechanical stability.

Typical defects in composite material production include:

  • Gaps / outstanding fibers in rovings and tows
  • Contaminations, e.g. particles, foreign fibers
  • Missing / wrong stitches
  • Fuzz balls
  • Irregular fiber distribution (thick / thin spots, holes / gaps)
  • Missing / broken threads
  • Streaks
  • Wrinkles

EasyInspect for composite material inspection uses  MIDA, ABI (Adaptive Background Illumination) and Virtual X-Ray technology to deliver optimum inspection results. The background illumination intensity can be adapted to different materials for perfect optical compensation of material noise. Combined with Virtual X-Ray, an illumination with ultra-high light intensity and high-power LEDs, this is especially effective for detection and classification of e.g. small foreign material inclusions.

EasyInspect and EasyMeasure for composite materials inspection can be used for many applications, such as

  • Rovings, tows
  • Carbon fiber / glass fiber mats
  • Carbon / glass non-crimp fabrics (uni- and multidirectional)
  • Carbon / glass fiber textiles
  • Prepregs
