This research work is focussed on the experimental complex shape forming of a flax fabric adopted as composite reinforcement. The fabric is a quasi-unidirectional woven fabric with thin twisted weft yarns connecting thick warp yarns using a warp rep weave interlacing pattern. The first part of the study is dedicated to the experimental measurement of the main deformation mechanisms of the fabric involved in forming processes: in-plane uniaxial and biaxial tension; in-plane shear; out-of-plane bending and out-of-plane compression. The second part is devoted to the experimental study of a complex 3D shape forming. The formability of the quasi-unidirectional flax reinforcement was observed using a double-dome punch in an open die forming process.

Abstract
This research work is focussed on the experimental complex shape forming of a flax fabric adopted as composite reinforcement. The fabric is a quasi-unidirectional woven fabric with thin twisted weft yarns connecting thick warp yarns using a warp rep weave interlacing pattern. The first part of the study is dedicated to the experimental measurement of the main deformation mechanisms of the fabric involved in forming processes: in-plane uniaxial and biaxial tension; in-plane shear; out-of-plane bending and out-of-plane compression. The second part is devoted to the experimental study of a complex 3D shape forming. The formability of the quasi-unidirectional flax reinforcement was observed using a double-dome punch in an open die forming process.File | Dimensione | Formato | |
