Résumé

Natural fibres such as flax are a promising replacement for synthetic fibres in polymer composites and achieve comparable specific properties due to their low density. Recent developments in the production of technical flax fabrics allow the use of sustainable natural fibres in the manufacture of structural composite parts. While biocomposites have been demonstrated to satisfy design and structural integrity requirements, it is suspected that one of the limitations of natural fibre reinforced composites is their impact resistance. In this paper, the impact behaviour of biocomposites made of commingled flax and polypropylene fibres is investigated. Composite plates were manufactured using compression moulding process. Processing parameters such as temperature, pressure and time were optimized to improve the mechanical properties of composite plates. Impact tests were conducted using an instrumented drop tower at multiple energies. Qualitative assessment of the impact damage and the energy absorbed were used to identify the different modes of damage and to identify the critical energy for complete penetration. The experimental study was supplemented with impact modelling of the biocomposite laminates using a commercial finite element software. There is good correlation between the impact response and the FE model.
