Summary

The primary objective was to fabricate, test and evaluate approximately ninety boron-epoxy tensile specimens containing embedded strain gages. Secondary efforts included improvement of the embedded strain gage design, investigation of embedded single-wire gages, investigation of strain gage embedment and interlaminar shear effects and reporting of materials property data. The results indicate that strain gages embedded in boron-epoxy composite laminates perform in the same manner and with the same quality and reliability as strain gages bonded to surfaces. Embedding the strain gages did not affect the laminate structural properties but the embedded gages were affected, in a few cases, during specimen curing.
