Comparison of different quasi-static loading conditions of additively manufactured composite hexagonal and auxetic cellular structures

Zhou, Jin; Liu, Haibao; Dear, John P.; Falzon, Brian G.; Kazancı, Zafer (Elsevier, 2022-12-27)

Auxetic cellular structures have the potential to revolutionise sandwich panel cores due to their potential superior energy absorption capability. Because of their negative Poisson's ratio, auxetics behave counterintuitively ...
Damage and energy absorption behaviour of composite laminates under impact loading using different impactor geometries

Ding, Yuzhe; Liu, Jun; Hall, Zoe E. C.; Brooks, Richard A.; Liu, Haibao; Kinloch, Anthony J.; Dear, John P. (Elsevier, 2023-06-24)

The present paper compares the damage and energy absorption behaviour of composites subjected to low-velocity impact using different frontal geometries for the impactor, with the composites possessing a layup of [02/902]2s. ...
Impact testing on the pristine and repaired composite materials for aerostructures

Hall, Zoe E. C.; Liu, Jun; Brooks, Richard A.; Liu, Haibao; Dear, John P. (MDPI, 2023-04-12)

Aircraft technologies and materials have been developing and improving drastically over the last hundred years. Over the last three decades, an interest in the use of composites for external structures has become prominent. ...
Strain-rate-dependent mechanics and impact performance of epoxy-based nanocomposites

Tüfekci, Mertol; Özkal, Burak; Maharaj, Chris; Liu, Haibao; Dear, John P.; Salles, Loïc (Elsevier, 2022-12-28)

Strain-rate-dependent mechanical properties and impact performance of manufactured epoxy-based nanocomposites are investigated. As reinforcements, fumed silica (FS) and halloysite nanotube (HNT) are used alongside Albipox ...
