摘要
为了改善大麻/聚乳酸复合材料的力学性能,采用不同质量分数的硅烷偶联剂KH550、KH580和AH151对大麻纤维进行表面改性处理,分析偶联剂种类及其质量分数对大麻/聚乳酸复合材料力学性能的影响。结果表明,KH550对大麻/聚乳酸复合材料力学性能改善最好,AH151对大麻/聚乳酸复合材料力学性能改善最小。偶联剂对大麻/聚乳酸复合材料力学性能影响的质量分数有一个临界值,当偶联剂的质量分数小于临界值时,大麻/聚乳酸复合材料的力学性能随质量分数的增加而增大,超过临界值后,大麻/聚乳酸复合材料的力学性能随质量分数的增大而减小。
In order to improve the mechanical properties of hemp/Polyactide(PLA)composites,the surface of hemp fiber was treated by different silane coupling agents KH550、KH580 and AH151,and the effects of coupling agents and their mass fractions on the mechanical properties of hemp/PLA composites were analyzed.The results showed that the mechanical properties of hemp/PLA composites were improved most by coupling agent KH550,and AH151 improves was least.The mass fraction of coupling agent on mechanical properties of hemp/PLA composites should have a critical value.When the mass fraction of coupling agent is less than the critical value,the mechanical properties of hemp/PLA composites increase with the increase of mass fraction,when the mass fraction exceeds the critical value,the mechanical properties of hemp/PLA composites decrease with the increase of mass fraction.
