在航空工业中,飞机设计中大部分都选用铝合金,而铝合金现在正面临着纤维增强聚合物(FRP)和近年来发展的纤维增强金属层压板(FRML)的挑战。这些新材料的质量轻、强度高,因此试图将金属和复合材料两者的优点结合起来,纤维增强金属层压板就是由纤维粘合剂预浸和铝合金薄板粘结而发展起来的。讨论了RRML的发展,叙述了市场上可买到的不同类型的FRML。对FRML的性能进行评价,特别是层压板的疲劳性能和缺口强度,主要讨论了聚酰胺层压板,但也谈到了玻璃和碳纤维基层压板,它们都优于聚酰胺基层压板。也讨论为模拟疲劳性能和剩余强度而推荐的模型。最后,根据以上讨论结果,推荐未来的研究领域。
In the aviation industry, the majority of aircraft designs use aluminum alloys, while aluminum alloys are now facing the challenge of fiber-reinforced polymers (FRP) and fiber-reinforced metal laminates (FRML) developed in recent years. As these new materials are lightweight and strong, attempts have been made to combine the advantages of both metal and composite materials. Fiber-reinforced metal laminates have evolved from fibrous prepreg bonding to aluminum alloy sheets. Discussed the development of RRML and described different types of FRML that are commercially available. The performance of FRML was evaluated, especially the fatigue properties and the notched strength of laminates. Polyamide laminates were mainly discussed but also glass and carbon fiber based laminates, both of which are preferred over polyamide based laminates. The model recommended for simulating fatigue performance and residual strength is also discussed. Finally, based on the above discussion, recommend future research areas.
