Abstract
A better understanding of wrinkle development in dry fibre forming processes can help select the most appropriate material and process parameters. This paper shows the evolution of wrinkles occurring in a single diaphragm forming process using novel time-resolved in-situ CT scanning. Forming trials were carried out using a representative curved C-spar geometry and a [0°/45°] Non-Crimp Fabric layup. A custom walk-in X-ray CT system allowed for the detailed 3D visualisation of the evolution and formation of subsurface defects. Results showed correlation between the waviness observed in the preform during partial vacuum and that in the fully vacuum and consolidated state. Overall, this study proves a methodology for in-situ CT scanning of a preforming process and shows the potential for time resolved in-situ CT to provide detailed information on the behaviour of dry fabrics during forming.
