Green laminate composites based on polypropylene (PP) and flax fiber

As the demand of green materials and green products are growing, the use of renewable resources and recycle materials are of great attraction. Natural fiber composites have been extensively studied during the last ten years. However, the main focuses were laminate thermoset composites and extrusion/injection composite products. New approach in fabricating thermoplastic composite parts and composite formulation with flax fiber at low cost has been developed to reduce energy consumption and improve the mechanical performance. The laminate composites were prepared by compression moulding. The results demonstrate that the formulation and the fiber treatment play important roles to the performances of the composites.
