Compression moulding of composites with hybrid fibre architectures (2016)
Journal Article
Corbridge, D., Harper, L. T., De Focatiis, D. S., & Warrior, N. (2017). Compression moulding of composites with hybrid fibre architectures. Composites Part A: Applied Science and Manufacturing, 95, 87-99. https://doi.org/10.1016/j.compositesa.2016.12.018

Advanced Sheet Moulding Compounds (ASMC) and unidirectional (UD) prepregs have been co-compression moulded to form a hybrid composite material. In-mould flow influences the UD fibre architecture in two ways. When UD fibres are aligned transversely to... Read More about Compression moulding of composites with hybrid fibre architectures.

3D geometric modelling of discontinuous fibre composites using a force-directed algorithm (2016)
Journal Article
Harper, L., Qian, C., Luchoo, R., & Warrior, N. (2017). 3D geometric modelling of discontinuous fibre composites using a force-directed algorithm. Journal of Composite Materials, 51(17), 2389-2406. https://doi.org/10.1177/0021998316672722

A geometrical modelling scheme is presented to produce representative architectures for discontinuous fibre composites, enabling downstream modelling of mechanical properties. The model generates realistic random fibre architectures containing high f... Read More about 3D geometric modelling of discontinuous fibre composites using a force-directed algorithm.

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
Evans, A., Qian, C., Turner, T., Harper, L., & Warrior, N. (2016). Flow characteristics of carbon fibre moulding compounds. Composites Part A: Applied Science and Manufacturing, 90, 1-12. https://doi.org/10.1016/j.compositesa.2016.06.020

This paper presents the development of a low-cost carbon fibre moulding compound using an automated spray deposition process. Directed Fibre Compounding (DFC) is used to produce charge packs directly from low cost carbon fibre tows and liquid epoxy r...

Optimisation of composite bone plates for ulnar transverse fractures (2016)
Journal Article
Chakladar, N. D., Harper, L. T., & Parsons, A. J. (2016). Optimisation of composite bone plates for ulnar transverse fractures. Journal of the Mechanical Behavior of Biomedical Materials, 57, https://doi.org/10.1016/j.jmbbm.2016.01.029

Metallic bone plates are commonly used for arm bone fractures where conservative treatment (casts) cannot provide adequate support and compression at the fracture site. These plates, made of stainless steel or titanium alloys, tend to shield stress t... Read More about Optimisation of composite bone plates for ulnar transverse fractures.
