The role of fiber reinforcement architecture in adjusting the mechanical properties of glass-fiber-reinforced epoxy composite materials is studied. Fibrous E-glass unidirectional (UD) and 3-dimensional (3D) samples with an identical fiber volume fraction were prepared. The UD composites displayed excellent properties along the fiber direction, but the 3D ones showed excellent properties in all three directions. The high delamination and impact resistances were additional advantages of 3D-reinforced composites to choose them as reliable materials for structural applications.

具有不同纤维增强结构的纺织复合材料机械性能的实验研究

研究了纤维增强结构在调节玻璃纤维增​​强环氧复合材料力学性能中的作用。制备了具有相同纤维体积分数的纤维状 E 玻璃单向 (UD) 和 3 维 (3D) 样品。UD 复合材料在纤维方向上表现出优异的性能，而 3D 复合材料在所有三个方向上都表现出优异的性能。高分层和抗冲击性是 3D 增强复合材料的额外优势，选择它们作为结构应用的可靠材料。
