Initial R-curves for translaminar fracture of quasi-isotropic carbon/epoxy laminates from specimens with increasing size (2021)
Journal Article
Xu, X., Sun, X., & Wisnom, M. (2021). Initial R-curves for translaminar fracture of quasi-isotropic carbon/epoxy laminates from specimens with increasing size. Composites Science and Technology, 216, Article 109077. https://doi.org/10.1016/j.compscitech.2021.109077

In this paper, a set of initial R-curves were measured for three different in-plane sizes using scaled Over-height Compact Tension (OCT) specimens and two different stacking sequences. The data reduction scheme was based on a Virtual Crack Closure Te...

Delamination suppression in tapered unidirectional laminates with multiple ply drops using a tape scarfing technique (2021)
Journal Article
Gordon, T., Xu, X., Kawashita, L., Wisnom, M. R., Hallett, S. R., & Kim, B. C. (2021). Delamination suppression in tapered unidirectional laminates with multiple ply drops using a tape scarfing technique. Composites Part A: Applied Science and Manufacturing, 150, Article 106627. https://doi.org/10.1016/j.compositesa.2021.106627

Composite laminate thickness tapering is essential for weight efficient structures. This is achieved by terminating specific plies, but these can in turn act as sites for delamination initiation. One area of importance is the spacing between adjacent... Read More about Delamination suppression in tapered unidirectional laminates with multiple ply drops using a tape scarfing technique.

The role of broken fibres on crack migration into 0° surface plies in adhesively bonded carbon fibre composite joints (2021)
Journal Article
Paul, A., Xu, X., Shimizu, T., & Wisnom, M. (2021). The role of broken fibres on crack migration into 0° surface plies in adhesively bonded carbon fibre composite joints. Composite Structures, 276, Article 114530. https://doi.org/10.1016/j.compstruct.2021.114530

Crack migration into the composite in adhesively bonded joints can cause a major degradation of strength. This usually occurs via cracks in the surface plies, but this paper demonstrates that crack migration can occur in joints even with 0° surface p...
