From fibre extraction to the composite manufacturing processes: Which path to adopt to maximise the mechanical properties of natural fibre based composites?

International audienceThis work proposes to analyse the different aspects that should be taken into account from the fibre extraction from plants to the forming process to achieve correct part forming. The study will focus in a first extent on the impact of the textile operations leading to the yarn manufacturing. The properties of the flax fabric will then be associated to its behaviour during experimental forming and related to the possible appearence of defects such as tow buckling and solutions to prevent its appearance is widely discussed
