Impact resistance and damage tolerance of scarf‐repaired composite structures: An experimental investigation
Source abstract
Abstract
The development and application of damage tolerance analysis of aircraft repair structures needs to keep pace with the growing of aircraft structural aging phenomena. The low‐velocity impact performance of scarf‐repaired structures is investigated experimentally in this article. The scarf‐repaired plates and the virgin plates were impacted using drop‐weight test machine at different impact energies. The time histories of impact force were recorded, and ultrasonic C‐scan technology was used to inspect the internal damage of the specimens. Permanent indentation, damage size, dissipated energy and the compression strength (strain) of these plates after impact are discussed contrastively. The results show that the impact resistance and compression behavior performances of prepreg scarf‐repaired plates are better than the virgin plates, while the performances of wet layup scarf repaired are the worst.
