Numerical and experimental analysis of the performance of the metal patch compared to the composite patch under aging conditions in water immersion
Source abstract
Abstract
This study investigates the mechanical performance of 2024-T3 aluminum plates repaired with metallic and composite patches under accelerated aging in water immersion. The adhesive and composite patch properties were experimentally characterized for various immersion durations and integrated into numerical models. Results revealed a substantial decline in stress transfer efficiency with aging, particularly for composite patches, which become less effective in absorbing stresses under humid conditions. Key factors, including loading type, crack length, immersion duration, and patch material, were analyzed. Stress analysis highlights the degradation of both the adhesive and the composite patch, leading to reduced load transfer from the damaged area. These findings show the critical impact of environmental conditions on the durability of bonded repairs and provide insights to optimize repair strategies for long-term performance. This work uniquely compares the performance of metallic and composite patch repairs on aluminum plates under aging conditions, highlighting the superior long-term durability of metallic patches in humid environments due to their resistance to water-induced degradation.
