Dataset for Experimental investigation of thermoplastic welded single-lap shear joints with a recycled core

This project contains supplemental data for the publication:

Arne Schiller, Chiara Bisagni (2026). “Experimental investigation of thermoplastic welded single-lap shear joints with a recycled core”. Published in the Journal of Thermoplastic Composite Materials.

The dataset is split into five folders:

1. “Code” contains post-processing code for generating the plots in the publication.
2. “T300PPS_Recycled” contains all data related to the induction welded T300/PPS single-lap shear joints with recycled core adherends.
3. “T300PPS_Virgin” contains all data related to the induction welded T300/PPS single-lap shear joints with virgin adherends.
4. “T700LMPAEK_Recycled” contains all data related to the conduction welded T700/LM-PAEK single-lap shear joints with recycled core adherends.
5. “T700LMPAEK_Virgin” contains all data related to the conduction welded T700/LM-PAEK single-lap shear joints with virgin adherends.

The top level file “Specimen_Nomenclature.xlsx” contains a conversion table for the specimen names in the publication and in this dataset.

Every folder contains an additional README file that describes the contents of the corresponding folder in more detail.
