摘要:

在不同冲击能量下采用落锤式冲击试验机对6种不同结构的层合板进行冲击实验,对冲击后的层合板实物进行损伤样貌观察,并通过扫描电子显微镜(SEM)观察了20 J冲击能量层合板的内部损伤形貌。结果发现,在相同的冲击能量下,(CGGG)s具有最高的极限载荷以及能量吸收。纤维混杂比相同条件下,冲击面为玻璃纤维时,冲击面纤维损伤程度更小;冲击面为碳纤维时,层合板能够吸收更多的能量。层合板冲击背面的损伤面积大于冲击面。通过SEM观察发现,碳纤维与树脂的结合性能优于玻璃纤维。但材料本身是复合材料层合板冲击性能的决定性因素,玻璃纤维更好的韧性决定了玻璃纤维比碳纤维具有更好的抗冲击性能。

Abstract:

The impact resistance of six types of structural laminates was investigated using a drop hammer impact tester at varying energy levels. Post⁃impact damage characterization was performed through visual inspection and scanning electron microscopy (SEM) observation at 20 J impact energy. Results indicated that carbon/glass hybrid fiber⁃reinforced epoxy matrix (CGGG) laminates exhibited superior performance, achieving the highest ultimate load and energy absorption capacity. Key findings demonstrated that: (1) under identical fiber mixing ratios, glass fiber impact surfaces showed less fiber damage while carbon fiber surfaces facilitated greater energy absorption; (2) the non⁃impacted backside consistently displayed larger damage areas than the impact surface; and (3) SEM analysis indicated stronger carbon fiber/resin interfacial bonding compared to glass fiber counterparts. Despite this interfacial advantage, the inherent toughness of glass fibers ultimately governed the impact resistance of the laminates, rendering glass fiber composites more impact⁃resistant than carbon fiber variants. These findings provide valuable insights for optimizing fiber⁃reinforced composite structures in impact⁃prone applications.
