Defect formation during preforming of a bi-axial non-crimp fabric with a pillar stitch pattern (2016)
Journal Article
Chen, S., McGregor, O., Harper, L., Endruweit, A., & Warrior, N. (2016). Defect formation during preforming of a bi-axial non-crimp fabric with a pillar stitch pattern. Composites Part A: Applied Science and Manufacturing, 91, 156-167. https://doi.org/10.1016/j.compositesa.2016.09.016

To capture the asymmetrical shear behaviour of a bi-axial NCF with a pillar stitch, a non-orthogonal constitutive model was developed and implemented in finite element forming simulations. Preforming experiments indicate that the local distribution o... Read More about Defect formation during preforming of a bi-axial non-crimp fabric with a pillar stitch pattern.

Flow characteristics of carbon fibre moulding compounds (2016)
Journal Article

Formability optimisation of fabric preforms by controlling material draw-in through in-plane constraints (2015)
Journal Article
Chen, S., Harper, L., Endruweit, A., & Warrior, N. (2015). Formability optimisation of fabric preforms by controlling material draw-in through in-plane constraints. Composites Part A: Applied Science and Manufacturing, 76, https://doi.org/10.1016/j.compositesa.2015.05.006

A genetic algorithm is coupled with a finite element model to optimise the arrangement of constraints for a composite press-forming study. A series of springs are used to locally apply in-plane tension through clamps to the fibre preform to control m...
