The effects of embedded fiber optics (FO) on the mechanical properties of a graphite/epoxy composite host material were studied. Optical fibers 125 micrometers and 240 micrometers in diameter were embedded in AS4/3501-6 graphite/epoxy, and the static performance of the material was evaluated. FO were placed in the midplane of the specimens both parallel and perpendicular to the loading direction. The mechanical tests included O degree(s) compression, 90 degree(s) tension, (0, +/- 45, 90)S tension, and first ply failure of (O2, 902)S specimens. Microstructural analysis of the fracture surfaces showed little influence of the FO on crack initiation or propagation. Test results showed no distinct influence of the FO on failure strength or modulus, but did open questions on the coupled effects of processing history, FO embedment, and failure strength.
