Description

This dataset contains data showing the effect of thin-ply reinforcement units, interlocked with a tab-and-slit geometry, on the fracture toughness of CFRP laminates. This dataset forms an addition to the dataset previously published here: https://doi.org/10.5281/zenodo.1476886. The previous dataset contains toughness data for reinforcements with tabs at 45 degrees. This dataset contains toughness data for reinforcements with tabs at 0 degrees.

The reinforcement concept was first presented at the 18th European Conference on Composite Materials (2018, Athens, Greece). More information on the concept can be found at: http://wwwf.imperial.ac.uk/aeronautics/research/pinholab/interlock-tabs/. Links to publications connected to this data will be added to the Zenoto meta-data as they are published.

For the reinforcement concept, both mode I and mode II fracture toughnesses were measured. The mode I data was acquired using DCB specimens, and the mode II data was obtained from 4-point end notch flexure (4ENF) tests. Force, displacement, crack length, and strain energy release rate during the test are provided for all specimens.
