摘要整理
天然纤维增强复合材料因其环保性、轻量化、低成本和低生产能耗等优势，在汽车、航空航天、建筑和海洋领域的应用日益受关注。天然纤维与玻纤混杂复合材料的结合可能开启新的工程和工业应用前景。本研究采用真空辅助树脂传递模塑法（VARTM）制备了麻纤维/玻纤复合材料，系统评估了不同铺层堆积序列对拉伸、弯曲和冲击性能的影响。采用三维X射线计算机断层扫描（3D X-ray CT）和扫描电子显微镜（SEM）观察了拉伸断裂试样的形貌失效行为。研究结果表明，复合材料的力学性能主要取决于麻纤维和玻纤的体积分数以及层板中的铺层序列安排。麻纤维体积分数增加导致力学性能下降，引发纤维断裂、基体开裂和纤维拔出等失效模式，这是由于纤维与基体间的粘结性能较差所致。复合材料中加入玻纤机织布虽然会在麻纤维-玻纤层间产生严重分层，但整体上提高了复合材料的力学性能。
