Abstract: Novel bionanocomposite material has been developed using nanoclay modified Spartium junceum L. fibres and PLA matrix. Its potential for the automotive industry was examined. Spartium junceum L. fibres were previously treated with montmorillonite nanoclay (MMT) and citric acid (CA) in order to enhance bionanocomposite thermal and mechanical properties to comply with the automotive industry requirements. After a macromechanics analysis, a comparison was made between experimental and theoretical modelling results. The evaluated tensile modulus and tensile strength of theoretical Hirsch model were in good agreement with those of the tested composites. Tensile strength and modulus of the newly developed advanced material were improved by 164% and 86% respectively, as compared to the pure PLA matrix.

Keywords: Spartium junceum L.; natural fibres; nanoclay; micromechanical modelling; automotive industry.
