Long discontinuous carbon fibre/polypropylene composites for high volume structural applications (2017)
Journal Article
Harper, L., Burn, D., Johnson, M. S., & Warrior, N. (in press). Long discontinuous carbon fibre/polypropylene composites for high volume structural applications. Journal of Composite Materials, https://doi.org/10.1177/0021998317722204

A processing route is presented to manufacture discontinuous carbon fibre reinforced polypropylene (CF.PP) composites, using much longer fibre lengths (25mm) and higher volume fractions (up to 45%) than previously reported in the literature. Carbon f... Read More about Long discontinuous carbon fibre/polypropylene composites for high volume structural applications.

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...

Inter-ply stitching optimisation of highly drapeable multi-ply preforms (2015)
Journal Article
Chen, S., Endruweit, A., Harper, L., & Warrior, N. (2015). Inter-ply stitching optimisation of highly drapeable multi-ply preforms. Composites Part A: Applied Science and Manufacturing, 71, https://doi.org/10.1016/j.compositesa.2015.01.016

An efficient finite element model has been developed in Abaqus/Explicit to solve highly non-linear fabric forming problems, using a non-orthogonal constitutive relation and membrane elements to model bi-axial fabrics. 1D cable-spring elements have be...

Heterogeneity of discontinuous carbon fibre composites: damage initiation captured by Digital Image Correlation (2014)
Journal Article
Johanson, K., Harper, L., Johnson, M. S., & Warrior, N. (2015). Heterogeneity of discontinuous carbon fibre composites: damage initiation captured by Digital Image Correlation. Composites Part A: Applied Science and Manufacturing, 68, https://doi.org/10.1016/j.compositesa.2014.10.014

This paper aims to identify architectural features which lead to damage initiation and failure in discontinuous carbon fibre composites formed from randomly orientated bundles. A novel multi-camera digital image correlation system was used to simulta...
