中文摘要:
      目的 研究液晶环氧树脂含量对E-51树脂体系固化性能和力学性能的影响。方法 采用动态DSC法, 研究了液晶环氧树脂对固化反应性的影响; 采用力学性能测试和扫描电镜的方法, 研究了液晶环氧树脂对固化物力学性能的影响, 及其增韧机理。结果 液晶环氧树脂含量越高, 树脂体系固化反应越快。液晶环氧树脂的加入使冲击强度、 弯曲强度和拉伸强度均得到提高。结论 液晶环氧树脂质量分数为7%的配方, 冲击强度和弯曲强度最高; 质量分数为10%的配方拉伸强度最高。
英文摘要:
      This work was aimed to study the effect of liquid-crystalline epoxy resin content on the curability and mechanical properties of the E-51 resin system. The effect of liquid crystalline epoxy resin on the curing reaction was studied using the method of dynamic DSC. The effects of liquid crystalline epoxy resin on the mechanical properties of cured resin and its toughening mechanism were studied by the method of tensile test and scanning electron microscopy. The higher the content of liquid crystalline epoxy resin, the faster the curing reaction. The impact strength, bending strength and tensile strength were improved by the addition of liquid crystalline epoxy resin. The bending strength and impact strength were the highest when the content of liquid crystalline epoxy resin was 7%. The tensile strength was the highest when the content of liquid crystalline epoxy resin was 10%.
