| 摘 要： | 分别以苎麻原麻和碱麻为增强体,KH550为偶联剂,制备了苎麻增强环氧树脂复合材料,研究了偶联剂用量和纤维含量对复合材料力学性能的影响,并对拉伸断口进行了观察。结果表明:当纤维的质量分数为50%,偶联剂用量为2%时,原麻/环氧树脂复合材料的力学性能最好,拉伸强度为172.9MPa,弯曲强度达365.4MPa;当纤维的质量分数为50%,偶联剂用量为3%时,碱麻/环氧树脂复合材料具有最好的拉伸性能,拉伸强度为117.3MPa;当纤维的质量分数为40%,偶联剂用量为3%时,碱麻/环氧树脂复合材料具有最好的弯曲性能,弯曲强度达293.2MPa。

| Abstract: | The ramie reinforced epoxy resin composites were prepared by using raw ramie and raw ramie treated by alkali as reinforced material and KH550 as coupling agent.The effects of the contents of coupling agent and fiber on mechanical properties of the composite were studied and the tensile fracture was observed.The results show that the mechanical properties of raw ramie/epoxy resin composite was best when the mass fraction of fiber was 50% and the usage amount of coupling agent was 2wt%,and the tensile strength was 172.9 MPa and the flexural strength reached 365.4 MPa.The best tensile strength of raw ramie treated by alkali/epoxy resin composite was obtained,and the tensile strength was 117.3 MPa when the mass fraction of fiber was 50% and the usage amount of coupling agent was 3wt%.The best flexural strength of raw ramie treated by alkali/epoxy resin composite was obtained when the mass fraction of fiber was 40% and the usage amount of coupling agent was 3wt%,and the flexural strength reached 293.2 MPa. |
