A method to improve the drapeability of Spread Tow Fabric (STF) of carbon fibres by introducing cuts to the fabric at the tow level is investigated. Two cutting patterns, different distances between the cuts and two cut sizes were trialled. The drapeability was assessed by means of optical scanning system (ATOS scanner) and a specially developed compliance test. The mechanical performance of the plates manufactured with the cut material was evaluated through a tensile test by measuring the stiffness and the strength in tension. The parameters that affect the drapeability and the mechanical performance were also studied. It was found that it is possible to tailor enhanced drapeability with a trade-off of the mechanical properties which might be acceptable for some applications. The reduction in mechanical properties varied with respect to the cutting pattern and to the distances between the cuts within the same pattern (the resultant fibre length).
