Abstract

This work presents the influence of deviations of fiber orientations of warp and weft yarns to the shear stress vs. shear angle behavior and the formation of wrinkles of fabric reinforced thermoplastics. FE results of bias-extension tests and the forming of a double dome part will be investigated with angular misalignment of the yarns and/or deviations of the blank to its loading direction. The prepregs or organic sheets may have imperfections like fiber misalignment or the prepregs of multilayered sheets are twisted against each other. Furthermore, there may be deviations to the idealized orientation caused by the operator or cutting machine for example.
