X-ray computed tomography data of expanded polypropylene bead foams of different density under compression

In this work, the morphology of three expanded polypropylene (EPP) bead foam specimens of differing density are studied using in-situ x-ray computed tomography. The specimens of 10 mm diameter and 10 mm length were cut from steam-chest-molded plates of 40 mm thickness. The plates are based on beads of different bulk densities (Neopolen (BASF) P92HD 105, 92HD 130, 92HD 180) and welded together in an Energy Foamer 5.0 of Kurtz Ersa using the crack-fill-method. The in-situ CT device FCTS 160 located at TU Dresden University of Technology, Institut of Lightweight Engineering and Polymer Technologie, with an x-ray CT setup rotating around the specimen and the tension/torsion-compression load train is used. The volume reconstruction is performed using CERA XPlorer (version 2.3.1. by Siemens) resulting to volume files *.vol and parameter files *.config. The provided data set enables the structure elucidation of polymer bead foam under compression.
