The aim was to compare the performance of the HMA with commonly used epoxy\u2010based structural adhesives in adhesively bonded composite joints. Composite single\u2010lap joints (SLJs) were used as test specimens, effectively representing adhesion quality and overall joint performance. Two epoxy\u2010based adhesives (paste and film forms) served as benchmarks, while the HMA was tested to highlight its advantages and limitations. All joints were evaluated under four\u2010point bending at various loading rates. Under static loading, the HMA showed comparable performance to the epoxy adhesives, although the failure mode shifted from delamination in epoxy joints to adhesive failure in HMA joints. Under high\u2010rate four\u2010point bending, the HMA demonstrated superior strength and toughness, reflecting its pronounced rate\u2010dependent behavior. Fatigue tests under four\u2010point bending were also conducted for all adhesive systems, and their performance was evaluated comprehensively. Furthermore, HMA SLJs initially tested under quasi\u2010static and fatigue loading were re\u2010bonded and retested under quasi\u2010static loading to assess performance after a second curing cycle, demonstrating the reusability advantage of the HMA. Overall, the study highlights that the HMA provides competitive static performance, enhanced high\u2010rate strength, and potential for re\u2010bonding, making it a promising alternative to conventional epoxy adhesives in composite joint applications. This work emphasizes the benefits of thermoplastic HMA in terms of mechanical performance, fatigue resistance, and reusability, supporting its adoption in advanced structural bonding of composites.<\/jats:p>","DOI":"10.1002\/pc.71055","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T13:10:02Z","timestamp":1775049002000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Behavior of a Novel Cyclic Olefin\u2010Based Hot\u2010Melt Adhesive in\n                    <scp>CFRP<\/scp>\n                    Adhesive Joints Compared to Conventional Epoxy\u2010Based Structural Adhesives"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3873-8791","authenticated-orcid":false,"given":"Hossein","family":"Malekinejad","sequence":"first","affiliation":[{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o Em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI)  Porto Portugal"},{"name":"Departamento de Engenharia Mec\u00e2nica, Faculdade de Engenharia (FEUP) Universidade Do Porto  Porto Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1933-0865","authenticated-orcid":false,"given":"Ricardo J.
