A flax fibre plain weave fabric has been used to form a complex tetrahedron shape. The global shape has been obtained. Globally, the complex tetrahedron shape was obtained, but tow buckling was observed in specific zones of the shape. The main mechanism at the origin of this defect has been defined. The influence of the fabric architecture has also been discussed and a solution consisting in specifically optimising the architecture of the fabric was proposed and tested with success to prevent the appearance of the tow buckling defect.
