Huo, L. (author), Kassapoglou, C. (author), Alderliesten, R.C. (author)To improve current design approaches for composite structures, it is required to further investigate the damage interaction effects of composite materials under multiple out-of-plane concentrated loads. It is first necessary to comprehend the dependence of the effective delamination threshold, which describes whether a delamination grows on pre...journal article 2023

Biagini, D. (author), Pascoe, J.A. (author), Alderliesten, R.C. (author)Although several studies have been performed, the compression after impact (CAI) failure of CFRP is still not entirely understood. It is still unclear what sequence of events determines the onset of failure in CAI tests and how the different damage modes are involved in this process. To experimentally investigate this matter, the present work...journal article 2023

Yao, Liaojun (author), Liu, J. (author), Lyu, Zhangming (author), Alderliesten, R.C. (author), Hao, Cui (author), Ren, Chuanxi (author), Guo, Licheng (author)Carbon-fibre reinforced composites are susceptible to delamination. Fibre bridging is an important shielding mechanism frequently observed in delamination. The presence of these bridging fibres can significantly increase interlaminar resistance, making it critical to represent this phenomenon for delamination characterization in composite...journal article 2023

(author)This study provides an investigation on mode I fatigue delamination growth (FDG) with fibre bridging at different R-ratios and temperatures in carbon-fibre reinforced polymer composites. FDG experiments were first conducted at different temperatures of R-ratios 0.1 and 0.5 via unidirectional double cantilever beam (DCB) specimens. A fatigue...journal article 2023

Quan, D. (author), Farooq, U. (author), Zhao, Guoqun (author), Dransfeld, C.A. (author), Alderliesten, R.C. (author)Carbon fibre/epoxy composite joints were assembled with Poly-etherether-ketone (PEEK) and Poly-ethylenimine (PEI) films using a co-curing process to prepare single-lap joint specimens. The joints were tested under quasi-static loading conditions at 22 °C and 130 °C and a fatigue loading condition. The experimental results demonstrated better...journal article 2022

Quan, D. (author), Wang, Guilong (author), Zhao, Guoqun (author), Alderliesten, R.C. (author)The inherently low surface energy of carbon fibre reinforced Polyether-ether-ketone (CF/PEEK) composites results in an extremely low compatibility with adhesives. This subsequently causes significant challenges in the adhesive joining of them to other dissimilar materials. Herein, the bonding surfaces of the CF/PEEK composites were treated by...journal article 2022
