Which of the following is a characteristic of rain erosion on fiberglass laminates?

Rain erosion on fiberglass laminates is a phenomenon where water droplets impact the surface at high speeds, commonly seen in aviation environments. When addressing the impact of rain erosion, the ability to repair is crucial in understanding how to manage and maintain the integrity of the laminate structure.

The correct answer emphasizes that rain erosion can indeed be repaired using resin. This is significant because it highlights the resilience of fiberglass materials and the fact that damage from rain erosion is not always permanent. Through the application of resin, which can fill the damaged areas and restore the surface finish, technicians can effectively restore both the appearance and some functional aspects of the laminate. It showcases a practical approach to maintenance in the field, promoting both the longevity and performance of fiberglass structures.

In contrast, the other choices reflect misconceptions about the nature of rain erosion. Suggesting that it cannot be fixed or that the entire laminate must be removed underestimates the repair capabilities available in the maintenance of these materials. Similarly, claiming that the damage is permanent does not account for the effective repair methods, such as applying resin, which can significantly restore the material's functionality and aesthetics.
