An Integrated Durability Framework for Hybrid Composite Joints in eVTOL Landing Gear under Hot, Arid Conditions

This dataset contains all experimental and numerical data supporting the study "Durability-First Design of Composite Hybrid Joints for eVTOL Landing Gear in Hot, Arid Environments" published in MDPI Aerospace (2025). It includes: Gravimetric moisture uptake curves from hygrothermal aging at 60°C/85% RH and 75°C/dry conditions, Dynamic Mechanical Analysis (DMA) thermograms used to quantify glass transition temperature (Tg ) depression, Mechanical test results for single-lap shear (SLS), double cantilever beam (DCB), end-notched flexure (ENF), and elevated-temperature hybrid joint tests, Processed statistical summaries (mean ± SD, 95% confidence intervals, p-values) for key metrics including shear strength knockdown (10.8%) and fracture toughness retention, Calibrated model parameters for cohesive zone modeling (CZM) and hygrothermal retention functions, Analysis scripts (Python/MATLAB) for reproducing Arrhenius time–temperature superposition, statistical inference, and CZM calibration. All data were generated at the King Abdulaziz City for Science and Technology (KACST) between January and June 2025 as part of the Institute’s eVTOL Materials Durability Program. The dataset enables independent validation of environmental degradation trends in composite hybrid joints and supports the design of certification-ready eVTOL interfaces for extreme climates.
