摘要: 为提高碳纤维层合板的抗冲击性能,采用三维中空机织间隔织物与碳纤维层合板一体成型,设计制备了不同原料(玻璃纤维、碳纤维)、不同厚度(3 mm、7 mm、15 mm)的间隔织物与碳纤维经编双轴向织物混杂增强复合材料,进行了9 J、15 J、21 J、27 J能量的连续低速冲击测试,并讨论混杂顺序对抗冲击性能及吸能损伤模式的影响。研究结果表明:间隔织物单侧分布时可以提供较大的初次冲击吸能,与单一层合板相比,比吸能值(Specific Energy Absorption,SEA)提升25.74%以上,27 J冲击时SEA至少减小33.67%,间隔织物厚度越大,吸能能力越强;碳纤维间隔织物的吸能能力高于玻璃纤维间隔织物吸能能力,27 J冲击时SEA减小21.46%。夹芯结构的吸能随间隔厚度增大而增大,且渐进冲击后依然有效,27 J冲击时15 mm玻璃纤维间隔织物夹芯结构SEA依然提升了2.48%;与玻璃纤维相比,碳纤维间隔织物夹芯结构的抗冲击性能更优,27 J能量冲击时SEA降低30.34%。

Abstract: To enhance the impact resistance of carbon fiber laminates, a three-dimensional hollow woven spacer fabric was integrated with the carbon fiber laminate through a integratedforming process. Various materials, including glass fiber and carbon fiber as well as different thicknesses (3 mm, 7 mm, and 15 mm) of spacer fabrics, and carbon fiber biaxial warp-knitted fabrics were designed and prepared as hybrid reinforced composites. Continuous low-velocity impact tests were conducted at energy of 9 J, 15 J, 21 J and 27 J. This study further investigated the effect of stackingsequence on impact performance and damage mechanisms. The findings demonstrate that unilateral distribution of spacer fabric significantly enhances the initial energy absorption. Specifically, the specific energy absorption (SEA) increases by over 25.74% in comparison to pure laminate configuration. At the impact energy of 27 J, the SEA experiences a reduction of at least 33.67%. An increase in the thickness of spacer fabric correlates with an enhanced energy absorption capacity. Furthermore, it is found that the energy absorption of carbon fiber spacer fabric is superior to that of glass fiber spacer fabric, with a 21.46% reduction in SEA during a 27 J impact. The energy absorption of sandwich structure is positively correlated with the thickness of spacer fabric and remains effective after progressive impact. At the impact energy of 27 J, SEA of sandwich structure with 15 mm glass fiber spacer fabric shows an enhancement of 2.48%. Additionally, the impact resistance of sandwich structure with carbon fiber spacer fabric, when compared at equivalent thickness, demonstrates superior performance relative to the glass fiber counterpart. At the impact energy of 27 J, the SEA for the carbon fiber structure is observed to decrease by 30.34%.
