Sandwich composites have been used as lightweight materials in aircraft manufacturing for a long time, from balsa wood sandwich the 1930s to honeycomb and fiber-reinforced polymers sandwich. Its characteristics are considered 'perfect' material aircraft, which has high strength with low density. common floor panels. The core is usually made of Nomex or aluminum honeycomb, while skin 1 "“ 2 ply ...

This paper reports the results of three thin wythe precast sandwich panels tested under axial load. Panel reinforcements and shear connectors in current state civil construction context are evaluated. The authors measured displacement at two distinct panel heights as well along width to provide load–displacement behavior cross-section level broaden experimental data on subject. test developed t...
