Flax unidirectional (UD) fabrics and Polyamide 11 (PA11) were used to create a 100% bio-sourced composite. First of all, flax UD fabric A and PA11 in the form of powder were superimposed and placed in a mould to create a composite. The process used for the transformation of the composite was thermo-pressing. The process parameters: temperature and pressure moulding were varied in different configurations. An optimal configuration was found by mechanical and DMA tests. Then, flax fiber UD fabric B and PA11 in the form of film were used to create a composite by film stacking method using process parameters of 210°C and 65 bars. The composite made of UD flax B/PA11 film presents the highest Young's modulus. Finally, by applying pressure levels of 25, 40 and 65 bars on UD flax B/PA11, the Young's modulus remains unchanged and the failure stress is increased. These mechanical results are in good accordance with the DMA analysis. [ABSTRACT FROM AUTHOR] |
