摘要

本研究的主要目的是研究纤维重量比和化学纤维改性对波西多尼纤维增强复合材料抗弯性能的影响。在不同的纤维重量比下，制备了未经处理和处理的波西多尼亚纤维增强的不饱和聚酯基体。结果表明，复合化学处理使复合材料的力学性能优于未经处理的纤维。纤维重量比影响复合材料的弯曲性能。事实上，当处理过的纤维增强复合材料的纤维重量比为10%时，其弯曲模量达到最大值。扫描电镜照片显示，Posidonia纤维增强聚酯复合材料之间的断裂表面不同。

Effect of Fiber Weight Ratio and Fiber Modification on Flexural Properties of Posidonia-Polyester Composites

The main objective of this research is to study the effect of fiber weight ratio and chemical fiber modification on flexural properties of composites reinforced with Posidonia fiber. An unsaturated polyester matrix reinforced with untreated and treated Posidonia fibers was fabricated under various fiber weight ratios. Results showed that the combined chemical treatment provided better mechanical properties of composites in comparison with untreated fiber. The fiber weight ratio influenced the flexural properties of composites. Indeed, a maximum value of flexural modulus was observed for 10% fiber weight ratio for composites reinforced with treated fibers. SEM photographs revealed a different fracture surface between Posidonia fibers reinforced polyester composites.
