Summary

The objective of this program was to conduct a series of tests for evaluating the effects of service environment on the strength of the boron/epoxy skins which are an integral part of the F-15 horizontal stabilator. Full scale static tests were conducted on two stabilators, and test results were compared with the capability of the F-15 stabilator demonstrated in previous testing. Moisture contents at various locations in the composite skins were predicted by evaluating the environmental histories of both test articles. Predicted contents were corroborated by moisture contents measured at conclusion of the static tests. F-15 deployments were projected for a 25-year service life, and moisture contents of stabilator composite skins were calculated for each projected deployment. Structural element tests were conducted under the maximum temperature and absorbed moisture conditions expected in service. Physical and chemical characteristics of the test article skins were evaluated relative to baseline boron/epoxy characteristics.
