Abstract

Alternative 'Double-Double' (DD) laminates have been proposed to replace legacy quad laminates (LQL), i.e. conventional laminates, due to potential advantageous design properties that such layups provide. However, limited analysis has been undertaken on these new laminates. This work presents comparative high fidelity computational finite element (FE) modelling of low-velocity impact (LVI) damage and compression-after-impact (CAI) strength of both 'Legacy Quad Laminates' (LQL) and 'Double-Double' DD laminates, using a validated FE modelling approach. An in-house intralaminar damage model and an established interlaminar cohesive model are used. Results show that DD laminates are effective replacements for UD LQL under both LVI and CAI loading conditions. It is shown that delamination damage may be reduced with DDs. Potential weight savings can be achieved with the use of DD laminates as well as simplifying manufacturing processes. In the cases presented herein, CAI residual strength increased with the use of a DD laminate over a traditional LQL.
