Semifinished textile stacks or preforms, useful in fiber-reinforced composites, contain superimposed textile sheets with fiber position and/or condition indicating elements for quality control
Production of semifinished textile stacks (10) and preforms, consisting of two or more superimposed semifinished textile sheets (12, 14), involves (a) laying upper sheet(s) (14) on a bottom sheet (12) and (b) determining the position and/or condition of the fibers, fiber bundles and/or filaments in the lower and/or upper sheet(s) using position and/or condition indicating element(s) (18) in the lower sheet(s) and/or indicating threads in the uppermost sheet.
