Nanocomposite films containing multi-walled carbon nanotubes (MWCNTs) were characterized for thermo-electrical behavior to assess self-heating. It was generally observed that maximum temperature increased with MWCNT and film thickness. To demonstrate potential for disassembly, glass fiber\/polypropylene adherends were welded with nanocomposite films. Shear stress during disassembly was measured for three initial adherend\u2019s surface temperatures. It was found that the required tensile load decreased by over 90% at the highest temperatures, effectively demonstrating the potential for disassembly via electrically conductive films. Fracture surfaces suggested that disassembly was facilitated through a combination of nanocomposite and matrix melting and weakened fiber\u2013matrix interface. Limitations, such as slow heating rates and the loss of contact at the interface, imply that the method could be more suited for recycling, instead of repair and reuse, as the heat-affected zone extended through the adherends\u2019 thickness at the overlap during heating.<\/jats:p>","DOI":"10.3390\/ma14102521","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T22:46:14Z","timestamp":1620859574000},"page":"2521","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Disassembly Study of Ultrasonically Welded Thermoplastic Composite Joints via Resistance Heating"],"prefix":"10.3390","volume":"14","author":[{"given":"Harry","family":"Frederick","sequence":"first","affiliation":[{"name":"Department of Mechanical and Industrial Engineering, Louisiana State University, 3261 Patrick F.
