| dc.description.abstract | Composites are materiais combining a strong reinforcement with a lighter matrix for enhanced mechanical and thermal properties. A typical example is the sandwich panei, comprising sturdy outer layers and a lightweight core, such as rock wool, enclosed between them. The outer layers can be metal, wood, or plastic. In paneis with polyurethane (PUR) cores, the bond between the PUR and metal sheets can weaken over time due to stress and fatigue, potentially causing structural failure. Researchers are actively exploring methods to enhance PUR and metal sheet adhesion. Their studies encompass surface treatments, optimizing injection conditions, refining PUR composition, and computer modeling of the material interface [1, 2]. Studies by Pereira et al. [ I ] highlighted that primers significantly enhance adhesion, whereas Naik et al. [2] explored optimizing the production process through tests to ensure robust and long-lasting adhesion. This study investigated the adhesion of PUR adhesives to metal sheets under real-world production conditions. The paneis were produced in a factory environment using ali the parameters and procedures to create a fundamental part. The study aimed to identify and categorize common adhesion defects (e.g., voids, weak adhesion) that may occur during production, additionally, it aimed to develop corrective actions to prevent these defects. The study involved performing pull-out tests on specimens taken from different positions on a large board and comparing the results with reference specimens without defects. | eng |
