The Effect of Ply Thickness and Notch Size in CFRP Tension Specimens
With the increasing application of fibre-reinforced composites into aircraft structures, understanding the effect of material and structural parameters on their damage behaviour is critical. An experimental investigation was conducted to study the effect of ply thickness and notch size on the damage of carbon fibre-reinforced composite specimens. Open hole tension and ply drop specimens in a range of configurations were tested quasi-statically until ultimate failure or the onset of detectable damage. The load response, damage modes and strain field development were experimentally recorded. The results demonstrated that changing the ply thickness and specimen dimensions markedly affected the damage modes and specimen behaviour. This key insight into the nature of composite behaviour is critical for the development and validation of analysis methodologies capturing damage initiation and progression.
