Abstract |
|
|
| This paper investigates the effects of chemical treatment and the reinforcement rate on the mechanical properties of polypropylene composites reinforced with Posidonia waste fibers. Increasing the reinforcement rate from 20% to 30% improved Young’s modulus and the flexural modulus of the composite. Silane treatment had a positive effect on all the mechanical properties of the composite; on the other hand, the alkali treatment improved the tensile strength but decreased the flexural property of the composite. The greatest Young’s and flexural moduli were obtained in the case of 30% reinforcement treated with silane. The increases in these properties were 57.95% and 44.84% for the tensile and flexural moduli, respectively, compared to pure polypropylene. The mechanical properties of the composite obtained were higher than those of hemp and jute produced under the same conditions using the single-screw extrusion process. The results show that Posidonia waste fiber is an effective candidate to be utilized to produce composites for the automotive industry, such as rear shelves, boot linings, spare wheel compartments, and interior doors, and that it has economic and ecologic advantages in comparison with hemp and jute fibers.
