Impact damage is a highly relevant source of damage for aerospace components, making low-velocity impact property an important consideration when integrating a material into the aviation industry for use in critical load bearing components. The material of interest comprises fibre metal laminates, which consist of a laminate structure of alternating aluminium and fibre layers. For this study, the low-velocity impact behaviour of two materials, namely ARALL and GLARE, both commercially marketed variants of fibre metal laminates were investigated. In order to evaluate the effects of incorporating different fibre types on the low-velocity impact behaviour of the resultant material, both fibre metal laminate specimens were fabricated using either woven aramid or S-glass fibres depending on the variant type; fabrication was also based on the hand lay-up method using uncured epoxy resin mixture of commercially marketed Epolam-5015 resin and Epolam-5014 hardener. In addition, monolithic S-glass fibre laminate specimens were also fabricated to provide a means of comparison.
