This paper presents one of the first experimental investigations to analyze the formability of dry woven
preform made of flax yarns. A defect analysis at the preform scale, such as wrinkling or buckling is
conducted. This work indicates the mechanisms at the origin of these defects. To form complex shapes
without generation of defects, the constitution and the architecture of the yarns constituting the woven
fabric should be optimised.
