Abstract

The blast response of a range of novel fibre-metal laminates (FMLs) based on fibre-reinforced thermoplastic composites has been studied using a ballistic pendulum. Here, FMLs based on stacked arrangements of aluminium alloy and two types of glass fibre reinforced polypropylene have been subjected to localised blast loading using a plastic explosive. The response of these lightweight FMLs has been compared to that exhibited by a thermosetting-based FML. An examination of the glass/polypropylene FML samples highlighted the presence of extensive matrix microcracking, delamination and localised fibre fracture in the composite plies, plus thinning in the aluminium layers. Some general failure modes def
