Automated analysis of defects in non-crimp fabrics for composites
M. Schneider, Toho Tenax Europe GmbH, Germany
Abstract:
In order to judge the textile quality of non-crimp fabric (NCF), a discontinuous laboratory testing method is developed, which is based on a digital image processing system. A flatbed scanner with an additional transmitted light device is used for the digital image acquisition of flat fabric reinforcement. In principle, the pixels of a digital image are similar to a map of numbers, which in this case range from 0 (i.e. black pixel) to 255 (i.e. white pixel). The user selects geometrical dimensions to be measured and the software analyses all pixels according to this selection. According to Airbus Industrie Material ...
