Abstract
Textile composite materials have large deformation characteristics, which leads to the superior formability. However, the large deformation of the textile preform is very much influential on the properties of the molded composite components. Hence, this paper aims at the measurement of large strain distribution in the complex shaped molded components of textile composites. A novel digital image-based procedure is proposed. The Green-Lagrange strain tensor is employed to express the large strain exactly and to avoid the misestimation due to the unmeasureable rotational motion during the closed molding. In pursuit of this, the deformation gradient tensor is calculated by the digitized information from the lattice pattern image drawn on the molded component. The proposed method is demonstratively applied to the deep-drawn components of rib-knitted fabric thermoplastic composites.
