Interlocked thin-ply reinforcements for improved fracture toughness and compression after

Experimental data shows the effect of interlocked thin-ply reinforcement units on the fracture toughness and compression after impact strength of CFRP laminates. The dataset contains mode I and mode II fracture toughness data from DCB and 4-point end notch flexure tests, and CAI data with post-impact C-scans and compression test results. The data was produced by John-Alan Pascoe of Imperial College London and the reinforcement concept was presented at the 18th European Conference on Composite Materials in 2018.

Use Cases

• Compare fracture toughness between reinforced and baseline CFRP specimens based on mode I and mode II test data.
• Analyze the effect of interlocked thin-ply reinforcements on compression after impact (CAI) strength using provided force, displacement, and strain gauge data.
• Validate computational models of composite failure using experimental measurements of crack length and strain energy release rate.
• Study the relationship between reinforcement unit geometry and post-impact damage visualized in C-scans.

Strengths

• Data includes both fracture toughness (mode I and II) and compression after impact (CAI) experiments for a holistic material performance assessment.
• Provides comparative results for non-reinforced baseline specimens and specimens with the novel interlocked reinforcement concept.
• Dataset is associated with peer-reviewed research presented at a major conference (18th European Conference on Composite Materials).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment for large-scale analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
