Abstract The aim of this study was to investigate the influence of the matrix properties, number of the carbon and aramid layers and fiber orientation on low velocity impact behavior of the fabric reinforced hybrid composites with stratified filled epoxy matrix. The impact tests were performed with the drop weight impact system at 90.629 J of energy level. The damage areas were analyzed by the visual inspection and tomographic images. The results showed that the matrix properties have a great influence over the fracture mode of the hybrid composites, while the fault degree of the damaged areas depends on the fiber orientation. The highest impact resistance was obtained in the case of hybrid composites with 0° ply orientation.

具有分层填充环氧树脂基体的织物增强混合复合材料的低速冲击响应

摘要 本研究的目的是研究基体特性、碳层和芳纶层数以及纤维取向对具有分层填充环氧树脂基体的织物增强混合复合材料的低速冲击行为的影响。冲击试验使用落锤冲击系统在 90.629 J 的能量水平下进行。通过目视检查和断层图像分析损坏区域。结果表明，基体性能对复合材料的断裂方式有很大影响，而损伤区域的断裂程度取决于纤维取向。在具有 0° 层取向的混合复合材料的情况下获得了最高的抗冲击性。
