| 摘 要： | 采用不同混杂比的碳纤维-玻璃纤维层内经向混编单轴向织物制备了混杂纤维增强环氧树脂复合材料,研究了不同混杂结构和不同混杂比的碳纤维-玻璃纤维/环氧树脂复合材料拉伸性能的变化及破坏形式。0°拉伸结果表明:同种混杂织物的不同混杂结构中,碳纤维相对集中的完全对齐结构强度最高,不同混杂比织物的完全对齐结构强度相当;碳纤维-玻璃纤维/环氧树脂复合材料的模量遵循混合定律。90°拉伸结果表明:纤维与树脂间的界面结合强度为碳纤维/树脂玻璃纤维/树脂,碳纤维-玻璃纤维/环氧树脂复合材料的强度、模量与材料厚度方向上界面的不同形式(单一或交替界面、碳纤维或玻璃纤维的分布位置等)有关,与碳纤维的含量基本无关。

| Abstract: | We use carbon fiber-glass fiber in layer knitting in the warp hybrid unidirectional fabric with different mixed ratio to prepare hybrid fiber reinforced epoxy composites, the tensile property change and failure form of carbon fiber-glass fiber/epoxy composites with different hybrid structures and different mixed ratios were studied. The 0° tensile results show that in different hybrid structures of same hybrid fabric, completely aligned structure with the concentrations of carbon fiber has the highest strength, the strength of fabrics with different mixed ratios of completely aligned structure is the same. The modulus of carbon fiber-glass fiber/epoxy composites follow the laws of mixing. The 90° tensile results show that the interface bonding strength between fiber and resin is carbon fiber/resin > glass fiber/resin, the strength and modulus of carbon fiber-glass fiber/epoxy composites relate to the different interface forms on material thickness direction (single or alternating interface, the distribution position of carbon fiber or glass fiber), and the content of carbon fiber has nothing to do with it. |
