Abstract: | The influence of the surface treatments on the performance of the hemp/PP (polypropylene) composite was investigated. The composites were prepared from the fiber modified by the alkalis and the oil under various conditions. The mechanical properties of the composites were measured using the tensile test, and the service time of the composite was assessed under accelerated condition by the stepped isothermal method. The alkaline treatment removed the lignin successfully and resulted in better fibrillation. The oil treatment improved the mechanical properties of the composites and extended the service life time of the composites. |
