The EddyCus® CF inline Series is especially designed for non-contact inline monitoring of carbon fiber fabrics. By using the EddyCus® CF inline Series, several lanes can be controlled. Consequently, the entire web of carbon non-wovens or UD tapes can be monitored during the production process.
Carbon fiber tri-axial fabric 200x200 mm². EC – scan (above) contain various information which can be separated into the individual layers.
Uniformity mapping is relevant for random structured carbon based materials. Here, accumulation of carbon fibers are shown darker. The EC-scan (above figure) shows small inhomogenities at the carbon fleece. A carbon fiber SMC is depicted (bottom figure).
The EddyCus® inline TOW roving monitor is a multi-purpose inline sensor specifically designed for the non-contact and continuous testing of carbon fiber tows, coated and metalized yarns, and metal fibers or filaments. The sensor is typically used to detect the homogeneity of carbon fiber tow. Detectable defects are splices, fuzz balls and the accumulation of fiber fuzz and surface roughness.
The EddyCus® CF inline GAP system is an inline system designed for the non-contact and continuous testing of non-crimp fabrics. A unique feature of the system is the ability to measure subsurface defects in a multi-layer stack. The sensor system measures the quality of the product and generates PDF-reports. The PDF-report shows NOK-regions to be cut before delivery. The inline GAP system is able to detect defects in inner layers, the location, length and width of gaps, missing layers, overlaps, carbon fuzz and much more.

The EddyCus® CF inline FAW is specifically designed for the inline monitoring of fiber areal weight of carbon fabrics. The spreading process of CF tows or processing of chopped fibers or non-wovens can be evaluated online without contact with fabric.

SURAGUS’ new EddyCus® CF inline ISO enables inline assessment of uniformity and isotropy (alignment) of discontinuous carbon fiber materials. For recycled carbon fibers (rCF) especially, decisive properties on product quality and integrity such as fiber orientation or degree of isotropy and the fiber distribution or weight uniformity are measured.
