abstract = "The effectiveness of through-thickness reinforcement at improving impact performance and out-of-plane tensile strength of fibre reinforced composites has been investigated. Two types of carbon fibre/benzoxazine composites were manufactured and characterised; one comprising a three-dimensional (3D) orthogonal fabric preform and the other a two-dimensional (2D) bidirectional 0°/90° non-crimp fabric. The materials were subjected to 6 J/mm of impact energy and damage areas were measured for damage resistance by a combination of penetrant-enhanced x-radiography and image processing. The impacted samples were thereafter tested to failure in compression to determine their residual compressive strength as a measure of damage tolerance. Lastly, a non-standard test method was employed to quantify tensile strength in the out-of-plane direction. The 3D-woven composite was observed to have higher damage resistance and damage tolerance. Furthermore, as expected, preliminary out-of-plane tensile tests showed a marked increase in tensile strength for the 3D-woven composite.",
