Aluminium foam sandwich panels containing aluminium alloy sheets (‘AFS’) have been made available now in sizes up to a few square metres but an unresolved problem in production is how to cope with non-uniformities of the foam and the general lack of mechanical property data of AFS. We investigate large industrial AFS panels and test X-ray radiography as a method to identify weak points in the foam core. For samples in which defects are identified, correlation with failure in tensile and bending tests is investigated. The properties of a large number of samples tested in compression, tension and bending are determined and presented in AFS property tables. We find that X-ray radiography has the potential to identify flawed and potentially weak AFS panels and can be used to test 100% of an industrial production output. The mechanical data measured for in total 120 samples provides a more reliable data base compared to the hitherto published sparse information.

包含铝合金板（'AFS'）的泡沫铝夹芯板现已面市，最大尺寸为几平方米，但生产中尚未解决的问题是如何应对泡沫的不均匀性和普遍缺乏的机械性能AFS的数据。我们调查大型工业AFS面板并测试X射线照相作为识别泡沫芯中薄弱点的方法。对于识别出缺陷的样品，研究其在拉伸和弯曲测试中与失效的相关性。确定了在压缩，拉伸和弯曲下测试的大量样品的特性，并在AFS特性表中列出。我们发现，X射线射线照相技术有可能识别出有缺陷的和可能较弱的AFS面板，并可用于测试100％的工业生产量。
