Elaboration by Wrapping Process and Multiscale Characterisation of Thermoplastic Bio-Composite Based on Hemp/PA11 Constituents

The present work investigates the potential of developing bio-composites based on thermoplastic polymers reinforced with natural fibres by using hybrid yarns. yarns were produced wrapping technique, in which a multifilament polyamide 11 (PA11) was wrapped around an untreated low-twisted hemp roving to produce yarn sufficient tenacity and stiffness for next step weaving. tensile behaviour identified both dry- thermo-state. Then, two different fabrics woven tested study influence densities weave diagrams flexural properties. At this fabric scale, properties made from compared those previous 100% roving. Composites these fabrics, stacking cross-plies, thermocompression characterised regarding mechanical strength.
