TECH FOCUS: LINE SCAN IMAGING
Carbon fibre inspection takes flight
Work is underway to build a vision system to detect defects in webs of composite materials
A
n inspection system for quality control in carbon fibre production
has been developed by a Fraunhofer institute for composite processing, together with camera maker Chromasens. Te line scan optical
measuring system was built as part of the AirCarbon project for SGL Carbon, a manufacturer of graphite and composite materials. SGL has been developing
high-performance carbon fibre suitable for aviation since 2011 from its manufacturing plant in Meitingen, Germany. SGL is also a leader in the AirCarbon project, funded by the Federal Ministry for Economic Affairs and Energy, in Germany, for industrial partners to develop

high-strength carbon fibres. It was joined in the project
by the Fraunhofer Institute for Casting, Composite and Processing Technology IGCV in 2014, to develop an optical inspection system with AI- enhanced image processing for carbon fibre quality control. Chromasens was brought
on board as a partner to provide the system’s line scan cameras and illumination systems, along with engineering expertise. Together with Fraunhofer IGCV, Chromasens developed
