摘　　要：本文研究了碱液及硅烷偶联剂对亚麻纤维结构与性能的影响 ,讨论了碱液及硅烷偶联剂浓度、亚麻预处理时间对亚麻 / L L DPE复合材料力学性能的影响。结果表明 :亚麻经碱液及偶联剂预处理后 ,吸湿率降低 ,热稳定性提高 ,结晶度和晶面间距下降 ,亚麻 / L LThe effects of alkali solution and silane coupling agent on the structure and properties of flax fibers as well as the effect of pretreatment of flax weave with alkali solution and silane on the mechanical properties of flax weave/LLDPE laminate were studied. The experimental results show that the moisture and the thermal stability of flax are improved, and the degree of crystallinity and the crystal face distance of flax are decreased after the flax weave is treated with alkali solution or silane. The tensile strength is increased from 84.8 MPa to 96.9 MPa, in case the fabric is pretreated with alkali solution. And the tensile strength, flexural strength and flexural modulus are increased from 84.8 MPa, 30.1 MPa, 1.95 GPa to 108.9 MPa, 64.6 MPa, 7.88 GPa after the flax weave is pretreated with A-151.
