High-velocity impact behaviour of hybrid-fibre engineered cementitious composite (ECC) panels subjected to an impact from a hardened steel, ogive-nosed projectile at velocities between 300-700 m/s is investigated and reported in this paper. The new ECC mix contains a proportion of 0.75% volume high-modulus steel fibres and 1.25% volume low modulus polyvinyl-alcohol (PVA) fibres. The mix is designed to achieve a desired balance between the strain hardening behaviour and impact resistance of material required for impact and blast resistant structures. The new hybrid-fibre ECC demonstrates its excellent capability for impact resistance and strong potential as a protective material with reduced impact damage and distributed micro cracking.

The compressive strength of C/SiC composite at different strain rates, off-axis orientations and after high-velocity impact was studied. The compressive strength was found to be 137 ± 23, 130 ± 46 and 162 ± 33 MPa at a strain rate of 3.3 × 10−5, 3.3 × 10−3, 3.3 × 10−3 s−1, respectively. On the other hand, the compressive strength was found to be 130 ± 46, 99 ± 23 and 87 ± 9 MPa for 0°/90°, 30°/60° and 45°/45° fibre orientations to loading direction, respectively. After high-velocity impact, the residual compressive strength of C/SiC composite was found to be 58 ± 26, 44 ± 18 and 36 ± 3.5 MPa after impact with 100, 150 and 190 m/s, respectively. The formation of kink bands in fibre bundles was found to be dominant micro-mechanism for compressive failure of C/SiC composite for 0°/90° orientation. On the other hand, delamination and the fibre bundles rotation were found to be the dominant mechanism for off-axis failure of composite.
