This study investigates the impact-energy absorbing potential of steel fibre reinforced composites with different matrices. The composites were subjected to low-velocity impact using the drop-weight impact test. The interfacial adhesion strength between matrices and steel fiber was characterized by a transverse three point bending test. It was found that factors such as fibre architecture, matrix strain to failure, and the level of adhesion can play a crucial role in the absorbed energy for penetration. A cross-ply non-crimp fabric showed higher energy absorption than a plain woven fabric. Absorbed energy increased with polymer matrix strain to failure and lower fibre-matrix adhesion.
