What cure temperature should be used in a field environment to mitigate moisture effects not removed?

The appropriate cure temperature to mitigate moisture effects not removed in a field environment is 210 degrees or below. This temperature range is critical because it ensures that the materials being cured will not be adversely affected by excessive heat, which could potentially damage the structural integrity or functional properties of the components.

Curing at or below 210 degrees allows for adequate evaporation of moisture trapped within the materials while preventing thermal degradation. Excessive temperatures can lead to issues such as warping, melting, or other forms of failure that compromise the aircraft's low observable characteristics. This balance is particularly important in maintenance environments where handling of sensitive materials is routine.

Other choices either represent temperatures that are too high, which could harm the materials, or prescribe conditions that are insufficient for effective moisture mitigation. Therefore, selecting cure temperatures of 210 degrees or below is essential for maintaining the integrity and performance of the aircraft structures involved in low observable applications.
