Abstract
Increased use of carbon fiber reinforced polymer (CFRP) composites in primary structural components of aircraft requires better understanding of their behavior, especially in the presence of damage. Reliable monitoring methods, providing stress or strain distribution data after damage and repair, are critical to safety and successful applications of CFRP composites for high-performance structures. This research will improve knowledge and demonstrate reliability of repaired CFRP composites. CFRP samples having adhesively bond repaired damage will be tested under uniaxial tensile loading. The strain field on the samples will be monitored using a digital image correlation (DIC) technique. This method will capture the strains over the entire surface of interest. The work will also provide data that shows how strain within a damaged sample is distributed, and how it affects the residual strength. Therefore, it is essential the behavior of a repaired carbon sample is known to improve the life of each repair and the design that it is a part of.
