Abstract

This research aims to understand the role of Z-binder weave architecture on the interlaminar shear behaviour and corresponding damage progression mechanisms in 3D woven orthogonal composites under cyclic shear loading. Two different structures: 2×1 and 2×2 twill 3D woven orthogonal composites have been investigated under short beam shear fatigue loading. The damage mechanisms have been evaluated by time-lapse X-ray Computed Tomography (CT) at different fatigue life stages. The primary damage mode is the delamination associated with fibre debonding and resin cracks distributed throughout the composites. The Z-binder is influential in delaying delamination propagation because it is subjected to a local tensile loading when the composite is under shear fatigue loading. The 2×2 twill Z-binder configuration provides better fatigue performance in comparison to 2x1 twill.
