通过在聚乳酸(PLA)生物基材料中添加亚麻纤维来增强其压缩性能,并探讨硅烷偶联剂浓度和亚麻纤维质量分数对PLA/Flax复合材料压缩力学性能的影响。首先,利用扫描电镜(SEM)对经硅烷偶联剂处理的亚麻纤维进行微观结构分析。采用熔融共混、注射成型的方法,制备了不同配比的PLA/Flax复合材料样品。再通过100 kN万能试验机测定了各样品的弹性模量和屈服强度。最后,利用扫描电镜对复合材料的截面进行微观结构分析,揭示材料内部的纤维分布和界面特性。研究发现:当亚麻纤维含量为5.25%且经过2%硅烷偶联剂处理时,复合材料的弹性模量达到最大值0.63 GPa,比纯PLA材料提高了24.2%;屈服强度提升至124.7 MPa,增幅达到15.6%。且,浓度为2%硅烷偶联剂处理的亚麻纤维与聚乳酸具有更紧密的界面相容性。
This study enhances the compressive performance of polylactic acid(PLA) bio-based materials by adding flax fibers, and explores the effects of silane coupling agent concentration and flax fiber mass fraction on the compressive mechanical properties of PLA/Flax composite materials. Firstly, scanning electron microscopy(SEM) was used to analyze the microstructure of flax fibers treated with silane coupling agents. PLA/Flax composite material samples with different ratios were prepared using melt blending and injection molding methods. The elastic modulus and yield strength of each sample were measured using a 100 kN universal testing machine. Finally, the microstructure of the cross-section of the composite material was analyzed using SEM, revealing the fiber distribution and interface characteristics inside the material. It was found that, when the flax fiber content is 5.25% and treated with a 2% silane coupling agent, the elastic modulus of the composite material reaches a maximum value of 0.63 GPa, which is 24.2% higher than that of pure PLA material. And the yield strength increased to 124.7 MPa, with an increase of 15.6%. At the same time,the flax fiber treated with a 2% silane coupling agent had a tighter interface compatibility with polylactic acid.
