Correlation between foam structure and mechanical performance of aluminium foam sandwich panels

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 production is how cope with non-uniformities of the and general lack mechanical property data AFS. We investigate large industrial AFS test X-ray radiography as method identify weak points core. For samples which defects are identified, correlation failure tensile bending tests investigated. The properties number tested compression, tension determined presented tables. find that has potential flawed potentially can be used 100% output. measured for total 120 provides more reliable base compared hitherto published sparse information.
