Abstract
This project studied the response of sandwich panel subjected to blast loading. The panels were based on two different face sheets (aluminium and woven glass-fibre/epoxy) and an aluminium honeycomb core. Experimental studies were carried out to analyse the effect of skin and core thickness on the blast response of the panels. The sandwich panels with glass-fibre/epoxy face sheets exhibited delamination in the face skin and core crushing, whereas failure in the sandwich panels with aluminium skins involved permanent visible indentation and core crushing. It was concluded that the composite-skinned sandwich structures offered a superior blast resistance to the aluminium-skinned system.
