研究了固化温度对苎麻纤维增强复合材料力学性能的影响,同时对比研究了平纹苎麻织物、单向苎麻纤维和单向玻璃纤维增强复合材料的力学性能.结果表明:环氧树脂3233分别在120℃,140℃和l80℃固化2h后,其拉伸性能和弯曲性能没有明显的变化；而基于环氧树脂3233的苎麻纤维增强复合材料在120℃和l40℃固化2h后力学性能相当,但是在180℃固化2h后,强度明显减小,模量变化不大；单向苎麻纤维增强复合材料的力学性能要远远大于平纹苎麻织物增强复合材料的力学性能,如单向苎麻复合材料uRamie-3233-120的压缩强度和压缩模量分别为154.0 MPa和35.6 GPa,而苎麻织物增强复合材料fRamie-3233-120分别为95.0 MPa和9.2 GPa;玻璃纤维增强复合材料的强度也会高明显高于苎麻纤维增强复合材料的强度.
