【摘要】 本文研究了聚乙烯稻草纤维复合材料的拉伸性能、弯曲性能和冲击韧性 ,并采用裂纹表面扩展功评价稻草纤维与聚合物基体之间的相互作用和采用扫描电镜直接观察其冲击断面稻草纤维在基体材料中的分布状态和被包裹状态。研究结果表明 :采用聚丙烯酸酯处理剂可以有效地提高稻草纤维在树脂基体中的分散状况 ;在复合材料体系中引入MAPE可以提高稻草纤维和聚合物基体之间的相互作用 ,提高材料的综合性能。更多还原

【Abstract】 The tensile property,bending property and impact toughness of PE/straw fiber composite were studied.Critical strain energy release rate was used to evaluate the interaction between straw fiber and base material and the dispersion and the coverage of straw fiber were directly observed by means of SEM.The results showed the polyacrylate treatment could improve the dispersion of straw fiber in the interaction between straw fiber and the base material,and the introduction of MAPE could improve the interaction between straw fiber and the base material and the properties of the composite.更多还原
