| 目的 研究混杂纤维复合材料在静载荷作用和拉-拉疲劳载荷条件下的力学性能及其在包装箱等领域的应用。方法 采用树脂转移模塑成型工艺制备5种包装箱用混杂纤维复合材料，并对试样进行拉伸性能和拉-拉疲劳性能测试。结果 纯C试样的拉伸强度高于C/G层内和C/G层间试样；在相同的铺层和织布方式下，C/G层内试样的拉伸强度高于C/G层间试样；纯G试样的塑性明显优于C/G层内和C/G层间试样，C/G层内试样的断裂伸长率高于C/G层间试样；C/G层内试样具有混杂正效应，可保证在具有较高强度的同时具备良好塑性。玻璃纤维在提高复合材料料板疲劳寿命上的作用要高于芳纶纤维，前者的刚度退化会低于后者，且碳纤维和玻璃纤维的层内混杂方式要优于层间混杂，层间混杂在复合材料抵抗疲劳损伤时具有正混杂效应。 |

| The paper aims to study the mechanical properties of materials under static load and tensile-tension fatigue loading conditions, and the application of hybrid fiber composites in packaging boxes and other fields. Five types of hybrid fiber composites for packaging boxes prepared by resin transfer molding were tested for tensile properties and tensile-tensile fatigue properties. The tensile strength of the pure C sample was higher than that of the C/G layer and the C/G interlayer. Under the same layup and weaving method, the tensile strength of the sample in the C/G layer was higher than of the C/G interlayer sample; the plasticity of the pure G sample was significantly higher than that of the C/G layer and C/G interlayer samples, and the elongation of the C/G layer samples after breaking was higher. In the C/G interlayer sample; the C/G layer sample had a hybrid positive effect, which can ensure good plasticity while having high strength. The role of glass fiber in improving the fatigue life of composite materials was higher than that of aramid fiber. The former had lower stiffness degradation than the latter, and the inter-layer hybrid method of carbon fiber and glass fiber was better than inter-layer hybrid. The composite had a positive hybrid effect when resisting fatigue damage. |
