摘要
Z-pin一般是直径很小的碳纤维杆,它被插入到复合材料层压板或接头厚度方向内,以便提高它们的层间性能。Z-pin增强技术在通过大量的试验验证后已被成功地应用到了一些航空复合材料结构上,但应用有限。本文综述了Z-pin复合材料的概念、制造方法以及Z-pin增强对复合材料层压板性能的影响,并对其未来发展方向做了展望。
Z-pins are commonly small diameter carbon rods.They are inserted through the thickness of composite laminates and joints to improve their interlaminar properties.Z-pin reinforcement technology has been successfully used in some composite aircraft structures through extensive experimental certification test,but its application is a limited number.The concept and manufacture methods of Z-pin reinforced composite laminates,and the effect of Z-pin reinforcement on properties of composite laminates are reviewed in the paper,and its development direction is prospected in the future.
