Finite element study of the microdroplet test for interfacial shear strength: Effects of geometric parameters for a carbon fibre/epoxy system (2017)
Journal Article
Zhao, Q., Qian, C., Harper, L., & Warrior, N. (2018). Finite element study of the microdroplet test for interfacial shear strength: Effects of geometric parameters for a carbon fibre/epoxy system. Journal of Composite Materials, 52(16), 2163-2177. doi:10.1177/0021998317740943

A 3D finite element model has been developed to identify the main causes of variability in the microdroplet test, which is commonly used to characterise the interfacial shear strength between polymer matrices and single filaments. A more realistic dr... Read More about Finite element study of the microdroplet test for interfacial shear strength: Effects of geometric parameters for a carbon fibre/epoxy system.

A water-soluble core material for manufacturing hollow composite sections (2017)
Journal Article
Xiao, Z., Harper, L., Kennedy, A. R., & Warrior, N. (2017). A water-soluble core material for manufacturing hollow composite sections. Composite Structures, 182, https://doi.org/10.1016/j.compstruct.2017.09.058

This paper presents the development of a low-cost water-soluble core material, which is suitable for producing hollow composite structures via high pressure moulding processes, such as compression moulding and resin transfer moulding. The bulk materi... Read More about A water-soluble core material for manufacturing hollow composite sections.

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.

Double diaphragm forming simulation for complex composite structures (2017)
Journal Article
Chen, S., McGregor, O., Endruweit, A., Elsmore, M., De Focatiis, D., Harper, L., & Warrior, N. (2017). Double diaphragm forming simulation for complex composite structures. Composites Part A: Applied Science and Manufacturing, 95, 346-358. https://doi.org/10.1016/j.compositesa.2017.01.017

A finite element (FE) model has been developed to simulate the double diaphragm forming (DDF) process, to identify potential defects when forming complex 3D preforms from 2D biaxial non-crimp fabric plies. Three different metrics have been introduced... Read More about Double diaphragm forming simulation for complex composite structures.
