It is noted that polyurethanes (PU) have lower processing temperatures and good impregnation ability; the impact strength of the PU laminate is 14.4% higher; PU-based samples are capable of absorbing higher impact energy (up to 32 J) compared to epoxy ones (up to 27 J). Visual analysis of the damage nature confirmed the higher impact resistance of polyurethane than that of the epoxy material. The authors suggest promising prospects for the application of reinforced composites based on urethane binders in infrastructure, shipbuilding, and the automotive industry due to their high specific stiffness, impact strength, durability, and corrosion resistance. Since high reactivity of PU binders complicates some manufacturing processes using them, a large number of patents are presented for methods that increase their pot life and gel time. Hybrid PU binders based on urethane (meth)acrylates with increased gel time, high mechanical characteristics, heat resistance, and minimal values of volatile organic compounds, obtained from isocyanates, polyols, acrylates, and other auxiliary substances, are considered the most promising. In the reviewed inventions, urethane acrylates with additives are considered as heat-resistant binders for fibrous composite materials that can withstand temperature effects up to 210°C during cathodic metallization, intended for the manufacture of automotive parts subjected to impacts and cyclic loads.</p>","PeriodicalId":741,"journal":{"name":"Polymer Science, Series D","volume":"19 2","pages":"244 - 251"},"PeriodicalIF":0.58,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148903252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
